However, if Vitalik dies, many things could happen either good or bad. Perhaps, Ethereum may fall if Vitalik dies, because he's been leading the project every step of the way. By not having a leader, the Ethereum project will disorientate itself into oblivion, IMO. Nonetheless, what are your thoughts about this?
I do not think so. Because Ethereum is a very popular currency, it no longer depends on the CEO, like bitcoin! Nobody knows who Satoshi is, but the value of Bitcoin continues to grow throughout the world, because there is power here. But if vitalik dies, then the development of Ethereum may stop or the price will not be the same, but its value will remain one of the 10 best crypt coins.
