a lot of people have felt that way even when Bitcoin's price was still below $500, and as you can see those who took the risk got rewarded for it.
it's never too late to invest, the only question is do you have the guts to take the risk and if you can afford to lose the money you will invest?

bitcoin is highly volatile and it is not for everyone, a lot of new investors get scared and cash out when Bitcoin's price suddenly drops resulting in them losing money, on the other side, a lot of new investors/traders take advantage of that volatility and profit from it, as I mentioned before, it is not too late and the only question is if you have the guts and money you can afford to lose to invest.
