This might seem very disheartening but the only time we see true parabolic movement is when bitcoin's mempool begins to fill, up until a point where it's pretty much unusable. This rinse and repeat cycle will continue until bitcoin core decides to convince their followers that it has no economic principle and absolutely no room for growth. For anyone who truly wants the best for this space, please be aware that no innovative  currency in this ecosystem is able to fulfill the  extent of the  functionalities it intended to provide. If a worthy currency had  the chance  to perform the job that bitcoin poorly does, then we wouldn't be having any of these drastic shifts in volatility. This obviously doesn't exclude exchange hacks and fake federal reserves providing liquidity to coins (tether) because that's a whole other contributor for these kind of drastic downtrends.
