You can use the strategy that suits you in trading. I do not like to use a strategy that is completely copied from other traders because every trader has a different situation and must use a flexible strategy that he can modify to suit his situation.
As for the stop loss strategy, it is of course good and useful in many cases, especially when the market is bearish, but I personally do not use it, especially with strong coins such as Bitcoin, as I prefer the hold strategy in the long term when the price falls instead of stopping the loss.
