Anonymint is totally overlooking counterparty risk of banks here and it makes 0 sense to me. Physical cash, Bitcoin, and gold is the only three things I'd want to hold during it. You cannot play carpet bagger and "buy the dip" of whatever asset using physical cash or gold because...you simply can't. You're basically advocating storing all your money in a bank as digital fiat of no value during the biggest financial crash in history with the objective of day trading it, which doesn't sound like a good idea to me.
I never said you should sell and wait for the dip. That is your decision to make. I also didn't say a V crash is certain, but rather contingent.
I didn't even get into counterparty risk of where to store your alternative value if one chooses to exit Bitcoin now in anticipation of lower prices later. You could definitely hold physical dollars ($20s not $100s) and probably be sure of being able to convert those back into BTC. But there are issues such as how much cash you can convert at a time and that does move you back through the anti-money laundering rigmarole.
Other options are to short Bitcoin. But timing is very critical and also exchange risk.
Personally if I still had any money (which I don't!) I would sell some BTC and hold dollars. Then I would prepare to buy gold < $1050 (probably $850ish) with the cash. Down the line I could convert that gold back to crypto again. If I got lucky to buy BTC < $150 with any of that cash, then I would do that.
In short, I'd diversify.
Not selling any of this deadcat bounce from $230 up to $470, is I think foolish. Always sell some of the rallies. Never HODL everything, except for heirlooms.
