No one is late in crypto world he/she just have to wait for the right time to sell their coins. Yes you are late for this bull run which is gone and in result bitcoin is trading currently at 54k$. So wait for bitcoin’s dump then buy coins as much as you can then hold for 6-8 months with you and then sell at good profit. If you want to invest right now then invest your money in other altcoins which has potential to grow in future.
