It was a good sell, even if it goes higher it won´t happen straight away. Crypto is volatile but it won't double prices over night, not that easy. If you are invested with your own money you really need to learn how to take profits, if you have already made lots of money then I think being a little bit more relaxed is fine.
ETH is your scar of the war, it is important to sell high because that´s the way markets work, sooner or later they will go down and correct themselves.
