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.
There's no age limit when using bitcoin even you're old or too young as long as you have basic knowledge in cryptos, you can use, have and earn bitcoin. It is to late if you miss the chance to use when you have time and don't waste your time to thing not important to you.
