At least 14 cryptocurrency exchanges were responsible for the loss of 1,195,000 BTC, according to the data. This number represents 6.3% of the 19.2 million BTC currently in circulation.

The data also shows that these exchanges have collectively lost $8.2 billion over the past seven years. The largest loss occurred in 2014, when Mt. Gox lost 650,000 BTC worth $473 million.

Other significant losses include: Bitfinex (120,000 BTC), FTX (70,000) Bitcoinica (61,000 BTC) and Celsius (105,000 BTC). Despite these losses, the overall trend seems to be positive, with the number of exchanges losing Bitcoin decreasing each year. This may be because exchanges have taken more regulatory and security measures in response to previous hacks.

Bitcoin, often praised for its deflationary properties, has a hard limit on its total circulating supply of 21 million. This is in stark contrast to fiat currencies, which can be subject to inflationary pressures. However, the sad reality is that a significant portion of the Bitcoin supply has been permanently lost due to the demise of cryptocurrency exchanges.

Over the past decade, many exchanges have been hacked and user funds stolen or lost. Also, many exchanges simply shut down, taking their users’ BTC with them. As a result, it is estimated that at least 5.7% of Bitcoin (1.2 million BTC) was permanently removed from circulation. While this number may not seem like much, it represents a significant portion of the total Bitcoin supply and highlights the need for better security and guarantees for cryptocurrency exchanges.

The need for transparent proof of reserves for cryptocurrency exchanges

As the cryptocurrency market has grown in recent years, so has the number of exchanges where they can be bought and sold. However, many of these exchanges have been plagued by fraud allegations and some of them have failed miserably.

The most recent example is FTX, whose CEO was accused of misusing customer funds, violating its own terms of service, and eventually filed for bankruptcy protection. This has led to calls for greater transparency around evidence of reserves.

The lack of clarity about the proof of reserves of exchanges is often cited as the main reason for their sudden collapse. Historical cryptocurrency crash data shows that 14 cryptocurrency exchanges lost a total of 1,195,000 BTC, or 6.3% of the 19.2 million BTC currently in circulation.

As the market continues to grow, exchanges must increase the transparency of their operations to increase user confidence and prevent another massive outflow of capital.

Mt. Gox is still #1 when it comes to exchanges that have lost BTC holdings

Jameson Lopp, co-founder and CTO of Bitcoin storage platform CasaHODL, conducted an investigation and found that Mt. Gox maintains its top position when it comes to exchanges shedding BTC holdings. While the scarcity of Bitcoin is directly related to its value as an asset, Lopp pointed out that fake Bitcoin offers are currently threatening the ecosystem.

He added: “Bitcoin will not be a good store of value if most people buy fake BTC.” The investigation confirmed that at least 80 digital assets have “Bitcoin” in their names simply to mislead investors. As a result, investors who buy fake Bitcoin assets have a negative impact on the original Bitcoin price appreciation.

Despite this, Lopp remains bullish on BTC’s future, noting:

“I still believe Bitcoin is the best bet we have to create a decentralized form of ‘sound money that can empower individuals around the world.”

To ensure Bitcoin’s position as “sound money”, self-custody is the most effective way to reduce dependence on crypto exchanges and corporate “Bitcoin paper” contracts.

Despite the recent crisis, El Salvador remains confident in Bitcoin

Salvadoran President Nayib Bukele announced plans to purchase 1 BTC every day starting November 17, 2022.

El Salvador currently holds 2,381 BTC at an average purchase price of $43,357. However, Bitcoin’s stagnant performance has given the country an opportunity to significantly reduce the average purchase price.

By self-custodial Bitcoin, El Salvador reduces its dependence on centralized entities and third-party intermediaries. By doing so, Bukele sends a strong message of support for decentralized finance and demonstrates that governments can play a role in the development of the cryptocurrency industry.
