No, it's not too late to invest in Bitcoin and cryptocurrency. At the moment it's just the start of Bitcoin and it'll much more develop in the future so I think you should take advantage to invest in Bitcoin right now cause Bitcoin is increasing very quickly and maybe this is the last time you can see Bitcoin price under 8k$ . But before invest in Bitcoin I think you should have some knowledge about Bitcoin cause it'll be very risky if you invest in Bitcoin without any experience and knowledge.
