No one can reliably know whether today is "early" or "late", because that requires predicting future prices. The ability to buy a fraction does not make the current price cheap or guarantee a future gain.
Before making your own decision, ask whether you could tolerate a large decline, whether the money has a near-term purpose, whether you understand custody risk, and whether your thesis comes from verifiable evidence or social-media emotion. Buying once, buying in stages and not participating all have trade-offs; staged buying does not guarantee a lower final cost or prevent a loss.
