No one knows for sure whether it is the right time to buy or not because the crypto market moves so fast. Recently Bitcoin experienced a decline after reaching a new ATH level, but it seems that this decline is only temporary as the Halving is getting closer. But if you believe that Bitcoin will experience a long-term increase during the halving, maybe this is the right time to buy and hold it until the halving occurs. All decisions are in our hands, therefore, never make decisions rashly, always monitor market conditions so that you can make the right decision.
In my opinion, I don't have a specific time of buying bitcoin, because if you are waiting for bitcoin to drop down before you buy, I don't think you are ready for making money on bitcoin. I mean, don't wait for anyone to tell you when to buy bitcoin, because no one can predict it, and it can increase and decrease, so the best thing to do is to just buy when you have money don't wait for the price to come down before you buy, Because when you are waiting for the coin to drop you are losing time because he cannot only drop once as a specific time.
So it is up to you to stick to your plan. Anytime you invest in bitcoin and the price drops, it is up to you to top up your investment so that when the price rises, you will undoubtedly make a large profit, and don't invest what you can't afford to lose because some people are making a lot of money, and you too, will decide to get like him and go spend money you can't afford. There are no obstacles to producing a profit, regardless of the amount you have you can invest and be profitable.
