But those who are competent investors have been investing mainly from the past, but if you invest in the present, the investment is usually long-term, so you can definitely get the maximum benefit in the bull market. It's only a matter of time before the price of Bitcoin rises to its highest level, and this is where the greatest profit can be made. So I will give most priority to present time investment, and those who invest will definitely succeed.
Past or present that's doesn't matter if you can invest in the bearish market and keep holding for the long term then profit will be maximum, I have experienced in this way but short term investors can not profit always because when they need to money urgently then they have to sell even at lower price from their buying price, most of the i lost for not holding long term.
