For me in practice, I hardly have made any serious gains from Bitcoin, Yeah, apart from using it as a payment medium for jobs I do for clients. Are there other ways people like us who are late adopters benefit from Bitcoin?
You are nowhere near as late as you claim, however the days in which you could use a small amount of fiat and get monster returns are over, still you can make way more money with bitcoin than with stocks and do so faster as well, after all I expect bitcoin to grow 100% or even 200% during this bull run, profits which are higher than what you can get with most stocks, so as long as the amount of money you invested was high enough, the profits you can obtain can still be very significant.
I agree, although bitcoin no longer generates millions of percent profits and makes many people rich from small capital. But finding 50% or 2x or 3x returns with bitcoin is entirely possible, whereas it would be very difficult for us to achieve that goal with other assets like gold or stocks. It can be said that we cannot get rich with a small capital using bitcoin these days, but we can make significant profits from it if we know how.
I think people who say it's too late to invest in bitcoin are greedy people, they want to be like the early bitcoin investors who wanted to get rich with just a small amount of capital. They want high profits but don't want to risk too much, they are greedy people.
