Very, very, very important
You must activate the stop loss at least 10% of the limit that the currency you are working on has reached, whether on immediate or futures contracts. The market may fall at any moment. There are very large price gaps between 70,000 and 80,000 for Bitcoin, and whenever the limit rises, I raise the stop price. The strategy I followed and it gave me huge profits. Even when the latter fell, my profits were not affected at all.
