DCA is always the best strategy with no hassle, but if the OP is looking for a strategy different from it, then he should wait until the market corrects, as that could happen maybe this year or next year. However, I just hope he won't regret his decision in case it turns out that the market stays bullish for years, but based on its historical trend, it doesn't move like that, so it's still nice to wait for the bear market.
The problem with waiting for the market to drop as low as possible is hard to spot. Because if ever Bitcoin drops already and this bull run is done, our minds will tell us that there's gotta be more with these drops. And that's another problem for OP and other potential investors to face because they think it's right and they need to wait more until they'll have hard time finding another good spot for buying. But if they follow the pattern, pretty much likely that 2026 is going to be it but we don't know, the market changes and it's always been unpredictable.
