Dogecoin is the second cryptocurrency based on POW, it does not seem to be the most destined to disappear
To be honest I am surprised that stuff like Dogecoin has not been hacked by now, because such altcoins are based on very outdated versions of older altcoins or Bitcoin itself. They are often many years behind in updates and failed to integrate many security patches.
2030 is just 5 years away, so odds are the coins mentioned by the OP will still be around with us. But I can't say the same for the next 10-20 years. Crypto land evolves fast, so anything can happen by then. Just "stick" to diversifying your investment, and there should be nothing to worry about.
The farther away the point in history, the fewer predictions you should make. You are more likely to be wrong on your 10-20 years predictions.
