In investing, it is never too late. If you get in early but can't hold for long, don't accumulate a lot of bitcoins, or don't make a big profit, then getting in early doesn't make sense. Investing is about making money, whoever makes more profit is not called slow or wrong.
They are not like us, individuals who invest just a small amount of money and take risks in an attempt to get rich quick. They are large companies and organizations with a lot of money, they don't need to rush or take too many risks.
