When you invest what you can afford to lose in BTC it will give you the boldness to create a daily budget or weekly budget in your BTC, because it will not make you to sell your BTC anyhow until it get to the price of your choice before you can sell to earn massive profits. I guess some hodlers will use this sudden dump to know that bear market is about to be stable for some weeks or months to allow both short time hodlers and long time hodlers to make use of the opportunity to add more BTC to their portfolio, because there will be great opportunity to make good profit.
The whole idea of "invest what you can afford if loss occurs" means that you do not have to sell when it goes down. So even if you bought at 120k, you can keep hold of it, and if you could buy some more at lower price that would be great. And while it's of course sad to buy at the top, if you can hold that means eventually price will go back up and you can make a big profit.
However, at this point people do not trust to have that kind of return, like 2x would be last time's ATH and there are some situations where it is not going to be the same. We need to make sure that we understand how we need to hold and do DCA if we bought at high price, and when it is crashing, doing DCA is somehow meaningful because all you gotta do is just buy a bit every month when you get paid and you are making use of cheaper prices out of commitment whereas others wait for further bottom which may never occur.
