you can see the struggle to make it there, for couple of times bitcoin took 65,000 and almost 69,000 but failed to reach 70k.
so yes it is a hardest but once taken surely there will another ATH.
I think the struggle is still on and today everybody thought bitcoin won't recover after price dropped down to around $55,200 and 300 and that created fear, but later the price moved back to $57k and trading at $58k this evening. I think is a struggle to continue bull to resistance $70k.
Many put their stop loss at $1000. The stops got run and it went back up.
Yes to understand how to apply stop loss is another trading skill on its own. It is not all trader that understand how to apply it and that is why some avoid it. Sometimes you apply it below or above and get more losses.
