As for sore losers, if they bought high without checking the record lows first and how long bear trends last, then it's their fault, don't blame Bitcoins.
People don't seem to care about that. They just look at Coinmarketcap and see whatever coin pump like mad for weeks, then jump in just because it has been going up already.
People have been blaming manipulators for the price to tank, and some even blame the CME futures. In other words, they are looking for excuses so that they have an external element or party to blame.
Some people will learn from what they have gone through, and others will keep making the same mistake again during the next leg up. The next time will be different they say, yeah right....
Hate to not only agree with you, but actually say that the blame game is played not only by the "average wannabe investor" but even by very popular self-styled full-time crypto traders selling signals. I've seen enough "whale channels" now to say without a doubt that almost everyone who's tried to make money off others (usually by selling their advice, signals, or audience attention) found someting else to blame.
They home in on their coins, and then make some chart and justification for it, so they can validate their buys. If the market moves correctly, they were smart and insightful and can teach you how to make the same smart moves full of savvy wisdom.
If they're wrong, they're calling out the manipulators, regulators, the irresponsible speculators, even the stock market.
And they and their audiences all think they're better than the average wannabe.
