With HashFlare you get earn 300-400% roi. But only now.
Firstly - New and surplus capacities. As reported on the official HashFlare sources, recently the company was engaged in the commissioning of another batch of new equipment in the data center in Iceland. Thanks to favorable conditions for the placement and supply of hardware, it became possible not only to continue the process of optimizing the service. Hashflare started big sale on surplus new capacities (not like discount. More like low prices). But it is very limited proposition.
So 300% ROI we already have.
Secondly - Promo discount codes. I won't start big tirade about generous actions of HashFlare. I usually get actual legit discount promocodes here, on the site: miningcrypto-online.com. Now they have a promocode on -15% discount sale, but there is a small possibility, that it isn’t working right now, because of reached limit of uses. I can't check it, because it was already in use by me, and it is disposable.
