For What.... Just my thinkig.
On the off chance that you are dead genuine about picking up a benefit on bitcoin, You should hold your ground and simply get back on your bitcoin one year from now or somewhere in the vicinity.
So you can Hold or you also can exchange!!!!!
In my opinion, the best thing to do when bitcoin is gradually falling is simply to hold, but if the price of bitcoin already reached your target price or value then I think that is the time when you have to sell some of your holdings, I think it is not a bad idea to sell bitcoin, it is a part of a strategy, and it is never wrong if you have already reached tour goal.
