According to CoinDesk, Bitcoin (BTC) has risen strongly by 11% in the past seven days, but some altcoins have risen even more, with some rising by more than 50%. The biggest gainer is VeChain's VET, which has risen by about 65%. VeChain is a blockchain designed to improve enterprise supply chain management and business processes. Although the catalyst for VET's rise is unclear, earlier this week the company announced that "account abstraction" has gone live, improving interoperability and unlocking programmable smart contract wallets. Kenny Hearn, chief investment officer of SwissOne Capital, said the chain is closely following Chainlink (LINK) in the on-chain oracle market. He said: "VeChain has met with multiple X2Earn projects in the past week, which has definitely brought additional bullish sentiment to the catalyst." Sei Network (SEI) rose nearly 50%, and Ethereum, the second largest cryptocurrency by market capitalization, rose 15%. As the price of Bitcoin approaches $53,000, the largest corporate cryptocurrency holder MicroStrategy (MSTR) has exceeded $10 billion in holdings and has made more than $4 billion in profits.
