Perhaps it may even be easier to explain how much you spent on your SHA-256 contract and what your ROI is to date. (Please give dates) Thanks

Hello fellow Steemer. I have a youtube channel that tracked my progress with Hashflare( which reminds me I need to make another video). I started with roughly 900 bucks. During that time the price obviously skyrocketed and the difficulty fluctuated as well. I broke even pretty early, and tripled my initial investment with using my earnings to exchange altcoin on Binance, Cryptopia, and the like. The youtube channel can be found here

Use coinwarz to estimate your ROI. It's kind of roundabout but you just convert your initial investment into Hashrate and from there plug it into coinwarz calculator to see your estimated payout(daily, weekly, monthly, and yearly).
