Which specific threat are you modeling against? A crash? A world war? Hyperinflation? A tyrannical government?

I cannot speak to crypto, but as far as the others go:

Gold is at 4988 today, MAX was 5626... beginning of November it was 4000, so in 3 months up 25%, what do I care about the max it was for 5 seconds.

Silver is at 88 today, MAX was 122... beginning of November it was 48, so in 3 months up 80%, what do I care about the max it was for 5 seconds.

DOJ is at 49500 today, MAX was 5328... beginning of November it was 47500, so in 3 months up 4%, OMG now I am mad! That is only 16% average a year.... With inflation at 3%, a real rate of return is only 13%. I can laugh all the way to the bank on that one.

This is why dollar cost averaging is a critical method.

I was discussing market crashes with a friend. He pointed out that it took like 25 years to recover from the great depression. Which he was correct, if you put ALL of your money in the just a minute before the crash. If you had been doing $100 a month for 2 or 3 years, your recovery was MUCH faster.

Crypto -- gold -- these are both assets classes where the price is primarily driven by speculation. Sometimes speculation causes prices to fluctuate up, other times speculation causes prices to fluctuate down. There's inherently no stability. Over the last year, the mass media has been filled with news articles about the gold price so it isn't surprising that a lot of speculators have jumped onto the bandwagon (or have been trying to jump off).

Some asset classes (stock, real estate, bonds) have intrinsic value based on the net present value of their associated future cash flows, independent of whatever price the market currently offers to buy or sell them.

If you're holding a heavy allocation of purely speculative assets and that's causing you to lose sleep, consider selling some and increasing your allocation to assets that have intrinsic value.

The US stock market is probably a bit overpriced at the moment, I'd avoid piling 100% into that. A reasonable split of US stocks and international ex US stocks could be appropriate if you're investing money that you don't need for a decade or more. There are lots of low-fee passively indexed ETFs that can be used to easily and cheaply invest.

"In the short run, the market is a voting machine but in the long run, it is a weighing machine." -- Ben Graham

The voting machine dynamic is speculation. The weighing machine dynamic is anchoring of prices around long-term intrinsic value.
