Vitalik is holding 550k ETH at the moment.
that is going to cause a serious issue in the future, if ethereum get big, basically we have a guy controlling it
so much for decentralization platform
550k of an ever-inflating currency is nothing. Right now there are about 5 times more ETH than there are BTC, and every year 20 more million are and will be created, ad vitam aeternam. Right now, 550k is 1/141 of the total ETH supply. Next year it will be 1/178, and so on and so forth.
Satoshi is rumored to hold more bitcoins, btw (about 1/21 of the total supply), and while there is a limited BTC supply, the ETH supply is unlimited.
Vitalik holds nothing. Right now his stack is worth $8,250,000 which is nothing. Even if ETH was worth $50 it would still be only $27,500,000. His dad has more than that in his bank account. That's nothing, especially for the man.
