My best way of earning bitcoin is through trading. yes its risky, yes it causes stress (alot), but i reckon you gain more after a while. I started low, like 1000 dollars, in 2017 and i just wait for the coins to increase in value. Sometimes they decrease too but i have made some profit with the coins. The real issue is when do you sell? I sold xrp when it reached 50 cents so im regretting that. Choose your poison carefully. i would suggest you do the signature campaigns but they pay peanuts like 10 dollars a week.
