I agree with you. But, for tax reasons, I will not cash out even partially. I have already exchanged my bitcoins for more than a dozen or so altcoins.

Bitcoin is a dinosaur. It has no working governance, it has a crippling scalability problem, not even SegWit seems to be supported by most miners yet, and it is very slow and expensive. Also, it is good to keep in mind that if there is no SegWit, there will be no Lightning Network, either.

I'm of the opinion that it is time to pay attention to utility or application coins that are part of a blockchain application used to solve some real world problem that requires a distributed solution.
