This is fine and good advice on any NORMAL market day.

However, all indicators of the future show NOT NORMAL being the norm.

Getting in or out of the market depends on people getting out or in. If one side isn't there, there is nothing you can do.

Dollar Collapse - its coming. When? Don't know, but all signs point to the edge of hyper inflation. When the dollar starts going, you won't have much time to buy... and there might not be much to buy.

Actual Adoption - its coming. We are at the beginning of actual adoption. And when that happens all the curves are accentuated. You thought things went up fast before? I can easily see bitcoin never hitting 10k this time around. It goes 4k, 5k, 6k, 9k, 100k.

Exchanges Are Trading Air it is apparent to many analysts that the exchanges do not have the coins they are trading. So, it is a game of musical chairs. And, if you wait to get a chair, you will lose out completely. No $s, no cryptos.

So, for these reasons, it may be better to HODL.
(or, a more appropriate term is cost averaging. keep stacking bits.)
