$25 Billion of Bitcoin
$25 Billion of Bitcoin Held by 7 Crypto Exchanges – Exchanges holding massive amounts of BTC only saw their reserves grow larger and data shows that Coinbase now holds 1 million BTC ($8.4 billion). Crypto users are still keeping large sums of digital asset holdings on trading platforms despite the fact that 2019 saw the most exchange hacks in one year over the last decade.
2019 saw a significant amount of trading platform hacks and exchange losses according to a recent report authored by the blockchain surveillance firm Chainalysis. The company noted that even though there were more attacks there was less money stolen. However, Chainalysis highlighted that malicious hackers are becoming smarter. “2019 saw more cryptocurrency hacks than any other year,” the report underlined. “But of the 11 attacks that occurred this year, none of them came close to matching the scale of major heists such as ’s $534 million Coincheck hack.” Last year digital currency exchanges lost approximately “$283 million worth of cryptocurrency” due to breaches and malicious hackers.
Despite the fact that 2019 saw the most exchange hacks people are still storing billions of dollars worth of cryptocurrencies on centralized exchanges.
Chain.info’s data showing that Coinbase holds 983,000 BTC but most of the data is fairly consistent with the findings from the Bituniverse application. Figures indicate that Huobi is the second-largest cryptocurrency exchange by reserve count with 462,000 BTC ($3.8 billion), 1.8 million ETH, and a large number of USDT as well. Binance has around 307,000 BTC ($2.5 billion) as of Saturday and 2.6 million ETH held in reserves as well. Then there’s Bitfinex (290,000 BTC or $2.8 billion), Bitmex (274,000 BTC or $2.28 billion), Bitstamp (242,000 BTC or $2 billion), Okex (211,000 BTC or $1.83 billion), Kraken (173,000 BTC or $1.8 billion), Bittrex (125,000 BTC or $1.2 billion), and Gemini (95,000 BTC or $922 million).
Proof-of-Solvency and the Recent Trend of Independently Recorded Crypto Reserve Lists
Other exchanges with a vast amount of digital assets held in reserves include Bitflyer, Gate.io, Poloniex, and Hitbtc. Bituniverse and Chain.info’s data shows that overall the centralized exchanges accumulated more reserves since the first week of December. Not only are a few crypto advocates afraid that large exchanges could be compromised for billions in digital assets by hackers, but there’s also the fear of fractionally reserving bitcoins.
Data from Chain.info is slightly different than the list provided by the Bituniverse application. Chain.info tracks the number of addresses and large deposits and withdrawals.
Proof of Solvency: Technical Overview
Solvency is defined as the ability of a company to meet its long-term financial commitments. Solvency is proved once the total reserve balance acquired using proof of reserves is shown to be sufficient to cover the total liabilities acquired using proof of liabilities.
During the last few months, platforms like Bituniverse and Chain.info have published reserve lists based on data provided by independent parties like Peckshield. Exchanges shown on these lists have neither confirmed or denied the bitcoin reserve data is legitimate. A number of community members within the cryptosphere believe trading platforms should provide their own reserve numbers so they can exemplify transparency themselves.
