Many posts discuss the possibility of exchange earnings with selling Bitcoin (and buy later). Other posts discuss the Bitcoin exchange rate, it seems that many agree there is a strong upward tendency and the volatility is hard to predict. It seems dat selling Bitcoin results in a serious probability of an opportunity loss. Selling Bitcoin can only be motivated by an (partial) exit. Do you agree?
This is entirely up to you. Bitcoin doesn't fluctuate very often, and it may continue to fall, two months ago. It's also likely to keep going up, as it did a few years ago, and I believe that selling bitcoin at a very low price was a very regrettable thing.
So it's up to you to decide, no one can predict the rise or fall of bitcoin prices.
