If you only want to invest for a couple of years, then i would recommend moving to another altcoin with a nice future, that way your investment would grow faster.
Your suggestions make sense. I totally agree with you. At the same time I wanna add something.
He can move bitcoin to alts but it is high risky though we know that high risk means high reward. But at this moment, he can maintain some strategies. For example, he can invest a portion of his portfolio to the alts. Then it will be a safe game I think!!!
