Definitely a good strategy, who ever bought bitcoins right after FTX bankruptcy must already be a happy investor today. You need to a have a strong stomach to buy when everybody is selling. The main issue is that we don't know how low the price is going to drop. I am sure there were quite a few investors who hoped the price would drop down to 10,000 USD and would have bought a lot of coins then. It's hard to really predict where the bottom is and when prices are going to rise again. I kind of stopped trying to find the exact points where to buy and sell. For me it's much more relaxing to buy my coins over a longer period of time. So instead of making one big purchase, I rather make 3-4 smaller purchases over 3 months. That might result in a slightly higher average purchase price, but I save some time on doing research to find the perfect time to buy.
