Cryptocurrencies will continue to be volatile, and the price would correspond with only what ordinary folks are willing to fork out. After all, the number of coins which can be mined are finite, which means it is expected that they will continue to grow in their value. Governments are not making life easy for cryptocurrencies though, as they have posed limitations and bans on financial institutions as well as their involvement with Bitcoin transactions, making the future extremely uncertain. No idea on what will eventually happen to Dogecoins, but there is a cap of 100 billion Dogecoins, which means each Dogecoin would be worth a whole lot less than (the 21 million capped) Bitcoins around.
