I wanted to add something else. The fact is that investing in bitcoin alone is too risky. Since it remains too volatile and therefore the adult audience can be overworked and sold not where necessary. In this you need to understand well and be able to make the right purchases. Sales. In addition to everything there should be an objective way to enter bitcoin, but for now it remains too complicated
Until you are dead, it's never too late to invest in cryptos. You can get unimaginable returns even within a year. I do hope it's BTc when you decide to invest.
