At this point in time, it is impossible to accurately predict the future price of Bitcoin. With that being said, it is generally recommended to buy Bitcoin when the price is low in order to maximize your ROI. This means that it is best to buy Bitcoin whenever there is a dip in the market. By doing this, you can capitalize on price volatility and benefit from any potential price increases that may come in the future. As always, it is important to remember to never invest more than you can afford to lose.
