Its a scam site / Ponzi Scheme Its a scam site, probably some type of "Ponzi Scheme". I invested about a $1000.00 and at first everything was great for I had no problem receiving my withdrawals, than after the 4th payment from them I stopped receiving anymore of my withdrawls/profits. I have tried contacting them several times with no response.

Would give 0 stars if possible Dealing with Smart Hashes has truly been the worst customer experience I have ever had with any company. They have simply not responded to several of my emails, and if they do, which is very infrequently, it is days later. I have deposited more than enough BTC on multiple occasions and they still refuse to activate my subscription. After dealing with this for weeks, I finally asked them to just send me my BTC back. It has been over a week since then and they still have not responded to me. I would give this product 0 stars if I could.

It's got to be a scam!! It's got to be a scam!!! A certain nationality thinks Americans are stupid. If you read the 5 star reviews you can easily see it's from people where English is not their first language. I saw it immediately. This is what makes these people stupid. They do not have the sense to have someone review their garbage for grammatical errors. I would say this is absolutely a scam, possibly Nigerian.

They don't give back afterwards Like all the others saying this, it's a scam I got my first few withdrawals for about a month and after that they just stopped sending me my withdrawals

Total SCAM they recently operated as… Total SCAM they recently operated as h2hashes.com that's where I too lost my money after buying two contracts 6 months for $6 and Flash for $375. Just like everyone else they have become unresponsive I've sent them many emails NO REPLY
