If you bought coins last summer when the price was 200$ then the answer is yes.
You made profit more than %100 and you can safely sell all.
If you bought after 400$, then don't bother. wait for 600$ at least.
Solid holders even keep holding their coins even while they have bought far below $300 last year. It requires you to have very strong hands in order to not secure profits at this point. If it's a smart thing to wait with securing profits in this case is another thing. Only time will tell.
well, if you have bought below $300 or like me at $190-$220 range, then there is no reason to sell right now. there is a long way to go from here and a lot of profit waiting. so unless you don't need the money there is no reason for selling bitcoin at this point.
I bought some in the middle of last year. I think the price of bitcoin will rise further. So I will not sell now.
