don't worry friend. haega at this time is very high but it can still go up again, bitcoin still has a long way to go. So hold on to your assets don't sell at a loss .. be patient if you want to get a profit. bitcoin still hasn't touched wave 5, so it's still safe now because it can still fly even higher.
If OP bought his Bitcoin during the dump (as he said), probably he is profit now. Is not to wonder why he is thinking about selling but because he is contented enough with how much he possibly get. I believe he is not a long-term holder, he can make a decision easier to make a sell but if he not in profit now, I don't think he does it.
Does holding for so long helps a lot? traders don't do that anyway. Buying and selling are their life, and that makes them become profitable.
