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?
Do you think their is no gain in bitcoin now? Or you think bitcoin only had gains then when it came new some years ago, their are good gains in bitcoin only if you can hodl bitcoin very well. The people you think benefited from bitcoin some years ago didn't get it for free but they were able to hodl bitcoin to male good profit from Bitcoin. During the last bear season the price of bitcoin went so low that if you had bought some bitcoin and hodl by now you will have a lot of Profit in bitcoin.
Many beginners just feel as they start engaging in bitcoin they will start benefiting from the profit of bitcoin very fast but that's not how bitcoin works, bitcoin doesn't make people to become rich very quick, you can only make gains only if you the patience to hodl bitcoin for sometime.
