On the other hand, decentralized exchanges (like all cryptocurrency exchanges) must maintain a fundamental level of user interest in the form of theta coin addresstrading volume and liquidity. Not all decentralized exchanges have been able to achieve these important baseline qualities. Further, users of a decentralized exchange may have less recourse if they are the victims of fraud than those who make use of exchanges with centralized authorities.

Marburg proudly calls itself a "Blindenstadt", a city for blind and visually impaired people, due to its long history as a hub for accessibility. A grocardano chart dollarund-breaking educational institute for the blind, the Blindenstudienanstalt (or Blista) in German, was founded here during World War One, to provide opportunities for young men blinded in the war. The institute has spawned countless inventions for blind people since then, including a tactile mathematical font. It has also profoundly shaped the town around it, turning it into a place where, as Portz puts it, "everything is ideal for blind people".Some of the innovations that make Marburg so accessible also exist elsewhere. But the way they are joined up here is unique, Portz and other blind people who have lived in the town say. The clattering sound of guiding canes is ubiquitous in Marburg, as blind people navigate the town aided by beeping traffic lights, pavements and floors with ridges and bumps that act as tactile signals of hazards or barriers. Buildings often have raised maps and floor plans, while detailed miniature bronze models of major sights such as Marburg's castle and town square allow blind visitors to feel the entirety of each landmark.

Other convenient features are a result of the town's natural shape. Marburg is small and hilly, making it easy to orient yourself simply by noting if you are going up- or downhill. A web of accessible leisure facilities spans the city, such as a horse-riding school for the blind, and blind rowing, football, climbing and skiing clubs. The town's university has Germany's highest proportion of blind students, and the widest range of degrees taken by blind people.The Blista and its students have driven many of these innovations, developing everyday aids such as a foldable cane, but also, working with the university to improve accessibility across departments. Law and psychology are among the most popular course choices, as the materials are text-heavy and can be studied easily with aids such as screen readers. Now teachers and pupils from the institute are prising open another field: the natural sciences, which have long been beset by barriers for blind people."I don't feel like a pioneer, but I guess I am one," says Portz, who is studying biochemistry and computer science in Düsseldorf. He is the first blind biochemistry student there, and by his own estimate, one of fewer than a handful of blind chemistry students in all of Germany.Chemistry remains relatively closed to the blind, due to the hazards of laboratory work, and the ubiquity of images, charts and graphs. But chemistry teacher Tobias Mahnke, who taught Portz at the Blista-associated Carl-Strehl-School in Marburg, argues there is no reason why his subject should be so restricted."No human being can see molecules, no human being can see atoms, and yet, chemistry education is so visual. Why? There shouldn't be any disadvantage for blind people, given that sighted people can't see all this, either," he says.

Mahnke, who is sighted, started working at the school in 2013. At the time, it didn't offer an advanced chemistry class. Since then, he and his colleagues have developed an array of multi-sensory tools and methods for teaching natural sciences, supported by the chemistry faculty at Philipps University in Marburg, as well as funding from the charitable Reinhard-Frank-Foundation. Mahnke has written a master's thesis on developing inclusive materials for teaching chemistry, and published some of his findings.Unlike conventional science models used in classrooms, the Blista models are designed to reveal entire processes and wide-ranging relationships. For example, a three-dimensional model of a water molecule, developed by a group of chemists at different universities, can be squashed flat, to encourage students to think about how it is depicted in two dimensions. A 3D-printed plastic model of a curving river bed, developed by Mahnke's colleague Tanja Schapat, is intended to be held under a tap. Students can feel where the water flows faster or slower, and how this shapes its contours. They then learn that where the bed is flatter, the water is shallower and therefore gets warmer in the sun, attracting fish and reeds.Related: Sen. Warren goes after Ethereum network fees in committee hearing

The DAO was one of the first major projects on Ethereum, launched in 2016 after raising $150 million USD worth of ETH through a token sale. The DAO was hacked due to code vulnerabilities and $60 million in ETH was stolen less than 3 months after it launched.It was one of the most heavily invested crypto projects to date, having attracted 14% of all circulating ETH at the time.As a result of the incident, the Ethereum community opted to hard fork Ethereum to reverse the attack, with dissenting voices maintaining the old chain to spawn the Ethereum Classic classic chain.Despite Bitcoin (BTC) dropping below the $43,000 mark on Monday, the outflow of BTC from exchanges has continued in a multi-month trend, particularly on Coinbase Pro.

Over the past month, the amount of Bitcoin held in Coinbase Pro’s vaults dropped by 28,843.87 BTC. Similarly, other crypto exchanges, including Kraken, OKEx, Bitfinex and Huobi, also experienced a drop in their Bitcoin holdings, with the withdrawn amount totaling 30,236 BTC across the board.On-chain analysts perceive falling Bitcoin reserves as a bullish signal.

That is primarily because most traders move their BTC assets to exchanges only when they prefer to trade them for other assets — be it fiat currencies or altcoins. As a result, the exchange balance serves as a metric to gauge traders’ sentiments for the underlying asset.As a result, Coinbase Pro’s declining Bitcoin reserves hint at its traders’ intention to hold BTC instead of selling it. But, at the same time, its top rival, Binance, has been playing a spoilsport.However, data also shows that the Bitcoin balance in Binance wallets has risen to 29,717 BTC in the last 30 days, which is more than the amount Coinbase Pro withdrew from its vaults.As the world’s leading crypto exchange by volume, Binance enjoys a certain influence on the market due to its global outreach. The exchange’s rising Bitcoin balances suggest that its users could sell an increasing amount of BTC, the opposite of the trend seen on Coinbase.

The increase in Bitcoin reserves on Binance also reached levels that followed up with the market sell-offs during the second quarter of 2021. Notably, the Bitcoin balance on the exchange spiked from 199,700 BTC on April 20 to 347,590 BTC on June 26.The same period saw BTC/USD drop from around $65,000 to below $30,000, including the notorious May 19 crash when Bitcoin plunged by more than 30%.Bitcoin trading at $300 premium on BinanceThe massive spike in Bitcoin reserves on Binance also coincided with premium BTC/USD bids on the exchange, with the BTC spot price being almost $400 higher on Binance than on Coinbase.

The vast price difference created arbitrage trading opportunities, coinciding with Binance’s Bitcoin reserves adding 1,529 BTC in the previous 24 hours compared to Coinbase that processed withdrawals of 579 BTC.As a reminder, exchanges still processed more than 30,000 BTC in withdrawals in the past 30 days, signaling that traders overall wanted to hold their crypto rather than sell it for other assets.

But given Binance’s trading volumes (~$24 billion) in the previous 24 hours were six times higher than Coinbase Pro’s (~$4.23 billion) at press time — as per data collected from CoinMarketCap — the probability of an interim Bitcoin price drop appeared high.Fall is traditionally the open season for United States financial regulators. The thicket of news coming out of Capitol Hill, federal courts and various regulatory agencies can feel overwhelming around this time, especially for those of us residing outside of these venerable institutions’ purview. It is also clear that the outcomes of these legal battles will have tremendous effects on crypto markets, adoption and, generally, the relationship between state power and the industry worldwide. But that is not the only reason for anyone interested in how the old world adapts to digital finance to follow U.S. developments closely.

Security and Exchange Commission Chair Gary Gensler appeared in front of the Senate Committee on Banking, Housing, and Urban Affairs last week. During the hearing, we didn’t get much clarity on how Gensler wants to handle stablecoins beyond his opinion that many of them “might well be securities.”It was good to at least see some senators, such as Pat Toomey, willing to call Gensler out for inconsistencies and omissions in his argumentation. What was worrisome was seeing mostly Republicans on the stop-stifling-innovation side and mostly Democrats on the stricter-investor-protection side (despite all the laughs and memes that Senator Warren’s Ethereum fees spiel produced). Crypto becoming yet another partisan issue is a nightmare scenario — luckily, it does not seem to be that way outside of this particular Senate hearing yet.The Commodity Futures Trading Commission, which has historically been more lenient toward the corner of the crypto space that falls under its jurisdiction, will soon have a permanent chairman and two new commissioners. All three nominees — the acting chairman who spoke amply in favor of innovation, a legal scholar specializing in digital finance, and another with a strong enforcement background — seem to have the potential to be a force for good for crypto, but let’s not get too excited just yet.The rest of the world keeps supplying major policy developments for digital assets. Cuba recognized cryptocurrency and now allows its use as a remittance and investment vehicle. Over in El Salvador, President Nayib Bukele’s opponents made a political statement by setting a crypto kiosk ablaze. In South Korea, the majority party clashed with the finance minister over a controversial crypto tax code, attempting to postpone its implementation. Notice a common theme? All over the world, cryptocurrency-related issues are part of political agendas.In the increasingly competitive landscape of blockchain technology and cryptocurrencies, protocol innovation and the ability to solve the biggest problems facing the crypto community are necessary for any project that looks to have long-term success in the ecosystem.Recently, the emergence of layer-2 technology like Arbitrum, Optimism and a bridge to the Avalanche ecosystem is revolutionizing the way investors, builders and developers interact with various protocols because each facilitates fast, low-cost transactions that improve the fundamentals of the decentralized finance (DeFi) ecosystem while also making it easier for retail-sized investors to capitalize on opportunities.

According to data from Token Terminal, DeFi continues to be one of the fastest-growing sectors of the crypto economy as evidenced by increases in the total value locked (TVL) on protocols. Some of the biggest gains from last week occurred on cross-chain compatible networks and layer-two protocols that offer a lower fee environment.Two of the top-6 projects on the list above, Trader Joe and Pangolin, are found in the Avalanche network which has seen significant inflows and an increase in TVL since the launch of an upgraded cross-chain bridge that allows Ethereum-based tokens and applications to migrate to the Avalanche ecosystem.

Governance features have also been a positive factor in helping spark new growth for projects as both Alchemix Finance and Rari Capital have ongoing, or recently completed votes designed to improve their ecosystems and increase community involvement.Another emerging trend shown in the data from Token Terminal is the growing strength of derivatives and options trading protocols as regulators increasingly crack down on centralized exchanges that offer derivatives services and have loose KYC and AML requirements.

As shown on the chart above, two of the biggest gainers in terms of protocol revenue over the past week were dYdX and Hegic, a pair of protocols that offer decentralized derivatives and on-chain options trading to investors.Global regulators have increased their scrutiny on leveraged and derivatives trading platforms in recent months, while at the same time, established exchanges like Coinbase have applied to offer futures trading services, indicating that this is one sector poised for continued growth as cryptocurrencies become more mainstream.

dYdX has also benefited from the fact that it operates on a layer-two solution developed in conjunction with StarkWare that enables cross-margined perpetual's with zero gas costs and minimal trading fees.Data shows that Ethereum-competitors such as Tezos (XTZ) and Cosmos (ATOM) have al seen an increase in revenue over the past week, suggesting that the layer-1 battle is heating up as high fees on the Ethereum network continue to motivate users to explore other options.FTX, one of the world’s largest cryptocurrency exchanges, continues expanding operations by inking major regulatory approval in The Bahamas.The Securities Commission of The Bahamas has registered FTX Digital Markets, the Bahamian subsidiary of the global FTX crypto exchange, as an official digital asset business, the firm announced Sept. 20.

The regulatory approval is granted under the Digital Asset Registered Bill of The Bahamas, the country’s new digital asset-related legislation that came into force in late 2020. Also known as the DARE Act, the legislation establishes a comprehensive regulatory framework for digital asset operations in The Bahamas, regulating and supervising virtual asset service providers.The regulatory approval will help FTX establish a “substantial presence” in The Bahamas as the exchange continues to expand its global presence. Ryan Salame, former head of over-the-counter trading at Alameda Research, has already joined FTX Digital Markets as CEO, and will be responsible for managing FTX’s local initiatives.

“The relationship we have fostered with local regulators culminating with us being authorized under the framework offered through the DARE Act, gives me confidence that we’ll be able to work closely with regulators to make sure our offerings are compliant in multiple jurisdictions,” Salame said.FTX did not specify what crypto services it’s planning to roll out in The Bahamas as part of its new expansion. Cointelegraph reached out to FTX and will update the story pending new information.

FTX is one of the largest crypto exchanges in the world, operating more than $3.5 billion in daily trading volumes at the time of writing, according to data from CoinMarketCap. The company has been actively expanding its operations and acquiring major industry players after closing a $900 million funding round in July. In late August, the company announced the acquisition of LedgerX, a licensed options and futures trading platform in the United States.Cryptocurrency assets held by institutional managers rose for a fifth consecutive week, a sign that market participants had once again flipped bullish on Bitcoin (BTC) and the leading altcoins.

Investment flows into crypto products totaled $42 million in the week ending on Sept. 19, with Bitcoin funds seeing inflows of $15 million, according to digital asset manager CoinShares. That’s only the third time in 16 weeks that BTC investment products saw positive inflows.All major assets registered a weekly increase, with investors buying up $6.6 million worth of Ether (ETH) products and $3.7 million worth of multi-asset funds. Investors also allocated $4.8 million towards Solana (SOL), disregarding a denial-of-service disruption earlier this week as a result of network congestion.In terms of actual products, 21Shares registered the largest weekly inflows at $28 million. The physically-backed crypto exchange-traded product provider now has $1.87 billion in assets under management. Grayscale remains the single largest crypto asset manager, with $43.177 billion in total assets.Fund managers have been buying up crypto in lockstep with a broad market recovery that began in late July. Crypto markets peaked above $2.2 trillion last week after plunging to around half that amount earlier in mid-July. However, by Monday, all major crypto assets had printed heavy losses as Chinese Evergrande news walloped risk sentiment.

Related: Bitcoin bounce levels extend to $36K with bulls unmoved by 8% BTC price dipInstitutional investors have become important players in the cryptocurrency market, which is a testament to the growing mainstream acceptance of digital assets. Some of crypto’s biggest asset managers told Cointelegraph earlier this year that investing in digital assets no longer carries the same level of career risk as before, which means more financial advisers and wealth managers are likely to enter the market. This was corroborated by a recent poll by London-based crypto fund Nickel Digital Asset Management, which found that most hedge fund executives have already purchased cryptocurrency.

DELIVERED EVERY MONDAYSolana has attributed the 17-hour outage it suffered last week to a denial-of-service attack aimed at Grape Protocol’s Sept. 14 initial DEX offering (IDO).

In a Sept. 21 blog post, the Solana Foundation stated that bots spammed the network as Grape launched its IDO on the Solana-based decentralized exchange (DEX) Raydium at 12:00 UTC last Tuesday.The botting activity overwhelmed the network with a transaction load of 400,000 per second, with Solana noting that “unbounded growth of the forwarder queues and resource-heavy blocks” resulted in a number of forks being automatically proposed to the network.
