When something is cratering like btc, the term is 'trying to catch a falling knife'
When it first broke below $40K, folks on different forums were saying "I'm buying more here". The same was said as various stops on the way down. It's $19,250 right now, so if those folks bought, then got hammered.
Sometimes it is best to 'let it breathe', even if one is fond of the entity. There were 'ambulance chasing journalists' in early 1990 when the Nikkei fell from 38,915.87 to near 30,000. They were right, however, as it continued to fall for years and fell below 8,000. 32 years later the ATH of 28-12-1989 still holds.
When the Dow crashed in 1929, it took until 1954 to set a new high, and that was only because the bankrupt companies were replaced in the index. A term arose from that time which folks still parrot, even though it was dead wrong ("Buy when there's blood in the street"). There was blood in the street, as folks jumped, but that was nowhere near the end of the bear market.
When the Hunts and Saudis gave up the ghost on Au/Ag in April 1980, it was 31 years before a new high, and $48 Ag fell to $3, $800 Au to around $270 in the interim.
Those things were either collections of productive enterprises, or else re the metals, something with a few thousand years of affection supporting it. It still took years and years to recover. I still think that even if any crypto survives, it will be one that corrects for what ails bitcoin, just as Google bettered Lycos, Facebook bettered MySpace, etc.
When speculative frenzies end, it varies from 'years' to 'never' to reach new highs. Whether btc $69K was the end of a speculative frenzy or not remains to be seen. I think it was, but that's why there are markets: opinions differ.
(ETH is bouncing off $1000. One try so far. Usually the 3rd try does it, and if it holds, a good bounce higher results.)
