There's plenty of poorly managed institutions holding a lot of Bitcoin right now. Many of them will eventually sell either because "they're super duper smart" and "will get ahead of the market" or because regulators and governments tell them to.

This means the price will most likely come back down before it reaches a new ATH.

I'm not suggesting trying to time the market, but just that DCAing will likely work for you as long as you don't give up.

Keep on it and keep stacking sats.
