No, selling everything would just not be smart, if you consider this with all kind of events that are upcoming this year.
The halving that is coming will let the price rise so you will lose profit when you are selling your bitcoins plus the bitcoin is getting bigger these days so that is also a reason to not sell the bitcoin at all.
Well selling all of your bitcoin yeah it is not a good decision that is why there is other way to make profit since bitcoin price is not stable our minds was confused but the is a way that you can be still get the profit if the price will continues to increase after you sell.. just sell 25%-50% of you bitcoins the rest sell it if the price will continue. if the price not continue you are lucky that you already make a profit so you can buy again bitcoin for a cheap price. .
