So guys I have started Ethereum Mining a year ago. Only focusing on Ethereum crypto. I have use around 6 Rx 570 4gb. But as per calculation I made it was taking around a year for returning my investment and after than there will be pure profit months. But I was not satisfied with it. So I started Mining different crypto which has low value now in market but store higher potential in future. Like ByteCoin. So after doing that for a months I have bunch of different crypto currencies with me. I decided to sell them all and count the income I made. I wonder that I made almost double the amount as earlier I was making in a month. Then I get into this. So I adapted this strategy. Also I later on decided to sell the rigs and switched to cloud mining. So my rigs are also sold out for about 3/4 th of the price I bought them. So I have earned around 180% profit in just 163 days. So yes GPU Mining worth it.
