What coins will be around in 20 years?

No one has a crystal ball, but I would love to know what coins you all think will still be around in 20 years. In my opinion the top contenders are proof of work coins.

I believe once proof of work coins gain enough traction and a large enough network is created they can’t be stopped. Game theory strongly supports this.

Coins that meet this criteria are: Bitcoin, Bitcoin Cash, Litecoin, and Dogecoin.

That’s just my opinion. Would love to hear everyone else thoughts and reasoning why their coins of choice have staying power.
