Thank you guys for all the replies 
So, I assume that long-term investing in ETH and all those ETH tokens are kinda risky, isn't it?
Why there is still more and more coins based on ETH when they all can be shut down so easily?

I think the answer is yes for every cryptocurrency, and ETH is more stable than most of them.
IMO the scenario of Vitalik deleting everything is unlikely... (I could think of other scenario that are more probable)
