It seems this story is not true according to Vitalik Buterin, as far as his story goes, but you never know. Vitalik is one of the most influential people in the cyrpto world, and he claimed he was not a crypto billionare and to prove it, he gave a connection to his largest digital wallet, which holds just around 365,003 ETH, and this sum is equal to around $73 million. Vitalik does confess to having different wallets, but he claims that they are very little.
