"Late" is subjective in this case because, people have different goals and holding periods, etc.
Comparing BTC and the Cryptomarket to other markets shows that BTC is still in it's infancy. Think of it as 1998 of the .com boom. Well, dont actually, decide for yourself. Thats how i picture it though. Maybe even earlier... All in all however, with a holding period for 1+ years and you will most likely make money. A lot of upside potential. Also alot of volitility in between lol. GL.
