What I earned yesterday with 22,5 TH/s:
SHA-256 payout (BTC) -->0.00280466 (39.44$)
SHA-256 maintenance (BTC) -->0.000567 (7.97$)
===========================
Result: 0.00223766 (31.47$)
0.00280466 --> 100%
0.00223766 --> X
================
X=79,78%
So... they charged me a
20,21% maintenance fee?? Are you kidding me??.

EDIT: LoL, a friend posted on Hashflare.io´s facebook, that how could they be charging a 20% maintenance fee, and they blocked him!!!!!!! LOL
This company looks like it´s just scam. Increased prices and now also charging a 20% maintenance fee??.
Amazing
