Stoploses very often leads to looses because in this unregulated market coins price can jump -20% in 1s to jump back to its backprice only to eat stoplosses.
But this is exactly how the market works and that is why the stop-loss orders are made, so that we don't blow up our accounts immediately but to blow that particular proportion we want to lose in a trade as stop-loss.
Imagine what would happen if the stop-loss are not in place and the jump happens?
