Wow, this is a great and positive news to hear about cryptocurrency, absolutely, there are some hidden billionaires in the crypto, but because they are not co founder, they may not be celebrated. Imo, becoming billionaires through crypto is a very easy thing, I came to understand that if an investor can buy at low price and hodl for about 2-3 years and at the same time compounding the profits, that would be incredible of him.
ETH is an awesome coin, and having the founder being so prominent and publicly available is great too. We are still wondering who the creator of bitcoin is, but with ETH we know it.
To me that's not necessary, the accomplishment of the coin to the public is necessary, Vitalik had allowed himself to be seen by the public because he want it to be so, of he has chosen to stay anonymous, eth will still do more better.
