All the gains with btc were made already if we are looking for 4 years from now is only 2-3x .
ETH I could see 5X in the next 4 years it has lower marketcap and better roi.
Maybe this is true but keep in mind the 3x increase in btc is worth a lot more than the 5x increase in ETH if it is dollarized.
But it is true that investing in eth is safer because there is less risk of sharp price declines compared to btc.
