Honestly, waiting for the "perfect" time to buy bitcoin is a losing game. No one can predict the market with 100% accuracy.
That's why people need to learn more about it and know that buying it, at any time, is worth it in the long time. No matter the price.
You know is easier to say than done, of course we can actually buy bitcoin at anytime as long as you're holding it for long term investment without paying attention to it's current value. Because anyone who is waiting for dip in the price of bitcoin before investing will definitely end up in regret, we still have the opportunity to start accumulating bitcoin as much as we can.
Moreover there's no best time to buy bitcoin as long as the capital is there, why those who don't have the capital to invest can wait till when they finally get the money to start up with. Because the reason why most people is finding it difficult to invest in bitcoin sometimes is due to lack of capital. and this also makes them think that is not yet time to invest in bitcoin, but I want to tell you that if this set of people have the capital to start up with. of course they won't hesitate to do that, reason been that they know that Bitcoin has a good potential in the future.
