Multiple governments want to have their own cryptocurrencies and bitcoin was recently accepted in ETFs (for investment) which is why its value it skyrocketing right now.
Stablecoins might become actually viable methods of payment or cryptocurrencies created by governments. But stuff like bitcoin, ethereum, and all the ethereum tokens, will probably never become used by a large section of the population for payments. The value just fluctuates too much.
What interests me most is the blockchain being used for voting. Wouldn't surprise me if that happened.
