The crash was an inevitability, as it always is when a market goes parabolic like the crypto market did last year. For those of us who were new to the market and got caught up in it, it can provide an invaluable learning experience. For most it will just lead to loss and for them to panic and quit on crypto.
Last year, the level of speculation reached to such unbelievable heights that everyone went under the sway effect of getting rich quickly and you can't deny the fact this time that they really had a reason to short it - not to make money, but to make Bitcoins. Every other crash that happened before was not an opportunity but just a loss, but this time, loss itself got transacted to huge profits for those who knew this was going to happen (as I said that correction was in talks during those days). Something that's yet to happen and we only talk optimistic won't really get us anywhere sometimes, but gives a chance to those who've got something more to bet on the negative side of that thing.
Whether motivated by gaining more fiat or more bitcoin shorting was still a great move when using hindsight. Even those of us who fully understand market cycles can easily lie to ourselves and say that the top isn't in yet. As always the top comes in before people actually think that it will, like wise the bottom comes in as people starting calling new lows.
