For some it maybe an attempt but still stop loss is considered as the best friend of most crypto traders, without it all your fund might at risk all the time.
People didnt tend to make use of it because once its triggered then its already considered as lost funds rather than having a pending order on negative which they do still believe that they can recover it out
or break even one the market had rise back up again.
It do have advantages and disadvantages though depending totally on market condition thats why you should know on when and not to use it.
