I can certainly see a possibility in that that happening. During the last cycle bitcoin went from 67k down to 18k which is ~73% drop. Let's say that in this cycle bitcoin goes up to 185k and drops down to 50k, that would make it once again ~73% drop.
We saw a ~73% drop last season, but I can't confirm that it will drop ~73% this season. It could be less or more. But this season, I hope we won't see much dumping. No matter how much Bitcoin's price drops, it's expected that it won't drop below $50k.
I think it will be considered cheap in the future to buy Bitcoin below 100.000$. Any opinions on that?
With that part I agree.
I agree that because Bitcoin is moving in the right direction, it's natural to think that. This will be considered in the future when considering the cheapness of Bitcoin.
