No, you are not late because you still have a chance to make money from crypto. When you are in cryptocurrency, your chance will not just come from bitcoin, but you also have a chance from altcoin, and your chance in altcoin will be bigger because, with so many altcoin lists, you only need to find and research the coin.
It is not easy to say I want to double $100 in bitcoin in the next year and make it to $100k in the next year because no one will know what suppose happen to bitcoin.
Once again, bitcoin is not a rich scheme way, but with having an effort to earn money from bitcoin and doing many things to earn that, you will have the opportunity to make money or double your investment someday.
