You should be warning yourself not to buy yet because things could go worse for now that fundamental news is making anyone anxious with what is going on in the economy.
I'd be DCAing when something good happens from then on like the stablecoin bill which is likely a good indication that more adoption to crypto will begin when this is approved.
Not everyone is paying attention to those news because most are continuously buying knowing that everything will still be fine on the long run. Why should one panic especially when he is holding his Bitcoin for over a decade ahead? If you panic especially this period that you should be aggressively buying more Bitcoin at lower price, then you are obviously investing for short term which is not a good way to go about Bitcoin.
As the correction started, I have been buying Bitcoin using my DCA method and whenever I have extra cash I buy more in addition to my DCA buying. This is because I want to take advantage of every opportunity the market is offering. I don't panic because I don't plan to sell now because I'm aiming for long term probably for as long as I earn income and have not retired.
