Selling of everything is just applicable if you don't have last option and you really badly need money for it. And for me if it comes for bitcoin.
Selling bitcoin is not going to be a good decision as the price of bitcoin is still not good as anyone is expecting. Just wait for more increase.
That will happen for the next month's.
Selling everything is not a smart move to make but never selling them also doesn't make any sense, if the current price is allowing me to make good profits then I will surely sell some part of it.
Sure, you are making good sense in your idea. I also do not believe that everything to be sold. At least if you want to make profit you should like 60% of of it if it commands good profit and keep 40% because you are not sure the price may still go higher which means more profit for you for not selling all at once.
