Don't you just hate when Genesis mining contracts are sold out? Especially when you purchased Bitcoin through Gdax to avoid fees inadvertently did so the Wednesday before Thanksgiving and had a pending $5000 USD balance for over a week while simultaneously watching Bitcoin rise from $8-$10k and realizing how had your funds been available earlier you could have profited 25% THE ENTIRE WEEKEND? (TL;DR - I bought Bitcoin at the wrong time at the wrong time). Anyway!
I always am always looking up coinwarz calculator to see cloudmining contracts, and it occurred to me that at least for Bitcoin, a simple multiplication of your average ROI divided by 12 (months) gives a fairly decent monthly payout estimate.
For Bitcoin mining contracts on Genesis, ROI is estimated between 224% (lowest) and 252% (stabilizes here around 40 TH up). For a $10,000 mining contract, rather than searching for a mining calculator, just multiply $10,000 * 2.52 = $25,200 Annually and $2100 monthly. (This factors in the 28% pool fee as well!) Beautiful, right?!
Of course, it's not perfect. But its something to think about when you're sitting in traffic or bored at work and want to crunch some quick numbers in your head! These prices will vary (obviously! Bitcoin stays on the rise). But better to underestimate than overestimate, right?
