It will never be like that, that was 80%+ drop that stayed like that for months, we still do have drops, just like very recently, but we are not going to drop 80% and then stay there for months. That was a very difficult period and it took us a lot of time to recoup those losses. I believe that we should not be worried about the price drops though, because we have seen that even during those times if you had absolutely no money at all, then you would be able to work for it, but if you had money then you would definitely bought some and profited by this time.
Even with the recent drop we are nearly 10x higher than the bottom of those periods which shows us how strong bitcoin is. Which means if there are big drops this year (which I doubt will happen any further) we could simply keep it going and buy more at the low price to profit later on.
We can't say that it will "never" be like that, but it does look improbable right now. I understand that people rather not see bitcoin drop too much ever again and whenever it is about to drop, people end up buying even more. Like just recently the crash wasn't from 52k to 46-47k levels, it was actually from 52k levels to 42k levels, it was a serious drop.
However from 42k to 46k it recovered very very quickly, like nearly instantly. The reason for that is the fact that we are were in a bull market and people are not willing to let it go just yet. We still had a bad day, the recovery didn't last very long, the 47k+ prices dropped to 46k again and equally in other coins as well. However the reason why I believe it will not be like 2018 is because we don't have the same feeling towards crypto as a community. However I still think it is not never", it could still be a small possibility.
