Honestly the title is a bit confusing, maybe it means what profit has brought or given by us through bitcoin or from bitcoin, but nevermind it depends on how we comprehend the question. Well i am not an early adopter but, since i have been in crypto, from ups and down trends of it that i have witnessed, it seriously brought me pretty serious amount of profit.
I have the same understanding from the title too, for me the profit I've gain from bitcoin helped me a lot financially despite not being an early adopter too. I saved a lot from the profit i gained from bitcoin despite of the price going up and down.
I also save some of my profit. But for now that the price of bitcoin is not good it's not ok for me to think what should I bought in mu profit because I just want to wait for long term to earn more profit then I'll buy if I already earn huge profit.
