There are so many cryptocurrencies in the market.
If one day the creators and developers of any of these currencies die or bancrupt, what will happen to the currencies? What will happen to the coins we have? Are the coins we have still worth anything?
Bitcoin? You do realize that bitcoins creator and developer is gone right? There is no one at the head of bitcoin writing a code for it like the first day, satoshi is gone and he hasn't been back for a long long time to do anything about bitcoin.
This is an obvious reason, why I would honestly suggest the same for all other coins, if a coin is a shitcoin and creator leaves than there is not much lost since it was already a bad coin but if there is a coin that actually might worth something and is on the road to be a great one but the creator suddenly vanishes than public could take it and build a great thing for it using the blockchain for implementing the new stuff (using that blockchain plus mining those blocks could change a coin totally like how we added segwit to bitcoin).
Crypto currencies are owned by the people, not the creators so it wouldn't be a big deal.
