Let share our experience.
As for me I still regret my actions years back, but I still believe that it's never too late.
If I had been fortunate enough to invest in cryptocurrency earlier, I am confident that I wouldn't have missed anything and wouldn't have any regrets since I know I would do anything to earn what people are making and that I would keep it till it made me money before I would sell. How come I'm saying this? Some folks don't currently own any bitcoin, but what I admire about them is that they always have the opportunity to purchase when the price is low and sell when the price reaches new all-time highs. They are good in that aspect, or perhaps I should say that they are lucky, but as you said, the present is what matters, so buy them now.
