The choice to buy Bitcoin depends on many factors and objectives. I would advise you to keep an eye on the whales, if they are draining bitcoins, then you can’t enter the market, if you can’t buy either, then they are speculating on its price, so that they can then cut off the profit from the hamsters. In general, a lot of factors depend on buying Bitcoin.
I don't think there's any need to watch the whales to invest in Bitcoin. Investing in Bitcoin always requires your own effort. If you aim to invest in Bitcoin then you can invest using DCA method if you don't have money to invest at once. In particular, I never trust the predictions of influencers to invest, I always invest using my own intuition, DCA methodology.
