my first big earning in crypto currency was in ethereum, though before this big pay came, ive been earning little amount of bitcoins from different faucets which i usually used in trading on poloniex when this exchange was still very popular, then, way back in 2016, i was trading and also participated in bounty campaigns on bitcointalk, i got lucky and joined this bounty which at the end, we were paid and i converted my tokens to eth and got about 7000 usd, this was my first big earning in crypto currencies at the time .
