Cryptowisser, a cryptocurrency services comparison platform, said in its annual exchange graveyard report that 79 crypto exchanges shut down in 2021, a figure it says exceeded the total from 2020. The company describes its database as one of the only extensive lists focused specifically on “dead” cryptocurrency exchanges. According to the report, the main drivers behind these closures included regulatory pressure, hacking incidents, and intensifying competition in a fast-growing market. It also noted that six of the exchanges in the report were closed because they were allegedly scams.
Regulation remains one of the biggest pressures
A central argument in the report is that wider adoption of crypto has brought greater government scrutiny. As digital assets move deeper into mainstream finance, regulators around the world are developing rules for trading venues, custody, anti-money laundering compliance, and user verification. For exchanges operating across borders or serving users in jurisdictions with shifting policy, these changes can quickly alter the economics of the business.
Cryptowisser argues that regulation can become a “kiss of death” for platforms that are unable to adapt. In some markets, tighter licensing standards or compliance obligations may make operations more costly. In others, outright restrictions on crypto activity can remove access to users entirely. The report cites the Chinese crypto ban as an example of a policy shock that hurt exchanges with exposure to that market, mentioning Bit-Z among the names that fell away in that context.
The broader implication is that exchange growth can no longer rely only on bull market momentum or retail enthusiasm. In a more mature market, survival increasingly depends on whether a platform can sustain the cost of compliance, maintain banking and legal relationships, and respond quickly to changes in national policy.
Hacks were fewer in number, but highly destructive
While hacking was not presented as the largest cause of exchange deaths, the report stresses that security failures still carry outsized consequences. It says there were three reported fatal hacks during the period it reviewed. Even if that number is smaller than the count attributed to regulation or competition, each such event can undermine trust overnight and make recovery almost impossible.
One example mentioned is Atomars, a Seychelles-based exchange that had been known for emphasizing security. According to the report, the platform suffered an attack described as an inside job and was unable to recover afterward. The case illustrates a recurring problem in crypto markets: technical security alone is not always enough. Internal controls, governance, and operational oversight matter just as much as code and infrastructure.
For users, these incidents reinforce a long-standing lesson in the digital asset industry. Exchange risk does not disappear during market expansion. In fact, strong trading activity can sometimes mask deeper weaknesses in operational resilience until a crisis exposes them.
Large centralized exchanges are crowding out smaller rivals
Another major theme in the report is the growing dominance of the largest trading venues. Even as the number of crypto users expands, smaller centralized exchanges face an increasingly difficult battle against global leaders such as Binance and KuCoin. The biggest platforms benefit from stronger brand recognition, deeper liquidity, wider product offerings, and higher user trust. Those advantages make it harder for newcomers or regional players to attract order flow and retain customers.
Cryptowisser frames this as a “powerhouse grim reaper” effect: major exchanges continue absorbing most of the new market share, while smaller businesses struggle to scale. The report points to the performance of exchange-native tokens as one visible sign of this concentration. It says Binance’s BNB rose from $27 a year earlier to $628, while the KuCoin Token climbed from $0.85 to more than $21. Although token price performance alone does not explain exchange closures, the figures are used to illustrate the rapid growth and market capture of the largest platforms.
In practical terms, smaller exchanges now need more than a basic spot market to compete. They must offer security, user-friendly onboarding, reasonable fees, market depth, and a clear value proposition. Without differentiation, they are vulnerable to being squeezed between regulatory costs on one side and the superior scale of market leaders on the other.
DeFi adds another layer of competitive pressure
The report also argues that decentralized exchanges, or DEXs, have been steadily pulling market share away from centralized venues. This trend reflects a broader shift in user preferences within crypto. Some traders are drawn to DEXs because they may offer lower fees, fewer KYC requirements, and greater control over assets. In an environment where self-custody and permissionless access remain core values for many users, decentralized trading infrastructure presents a meaningful alternative.
To illustrate this growth, the article highlights Uniswap. According to the figures cited, the token’s market capitalization expanded from nearly $900 million a year earlier to $15 billion. The number is presented as evidence that DeFi platforms were capturing both attention and economic value at a pace that centralized competitors could not ignore.
This does not necessarily mean decentralized exchanges will replace centralized platforms across the board. Centralized venues still dominate many areas, especially where fiat on-ramps, customer support, and compliance are essential. But the report’s point is clear: smaller centralized exchanges are no longer competing only with larger centralized rivals. They also face pressure from DeFi protocols that can attract users with a different operating model and a lower-friction trading experience.
A maturing market with higher barriers to entry
In its concluding remarks, Cryptowisser suggests that the rising number of exchange closures reflects an industry that is becoming harder to enter and harder to survive in. The days when a team could launch an exchange in a bull run and hope momentum alone would carry the business appear to be fading. In a more developed market, exchanges need sufficient capital, robust compliance systems, reliable security, and a competitive edge that goes beyond simply being available.
The company also suggests that, over time, regulation could help stabilize the number of exchanges in the market. That is not presented as a short-term benefit for every operator, but rather as a sign that the industry may be moving toward a smaller group of better-capitalized and better-prepared platforms. In such an environment, survivability depends on a blend of legal readiness, operational discipline, and strategic positioning.
For market participants, the report serves as a reminder that exchange selection remains one of the most important risk decisions in crypto. A booming market does not guarantee that every trading venue will endure. Behind the headline of 79 exchange deaths in 2021 lies a broader story about industry consolidation, evolving regulation, and the growing influence of decentralized finance.
The original source material was published as a press release, and its conclusions reflect Cryptowisser’s own data collection and market interpretation. Even so, the report offers a useful snapshot of how competitive and unforgiving the crypto exchange business had become during that period.
