I bought one of their smaller packages… I bought one of their smaller packages to test and they made 3 payments. It's been since 9-22 and they haven't made any more payments. They get you in and then rip you off. Don't invest!! I'm going to Feds with this, and filing with the State Attorney General.

Exit Scam Exit Scam. Submitted complaint to FTC. Invested on 8/31/21. Requested modest withdrawal on 10/16. Status pending three days. Website shutdown 10/18 ~10/19. Sent email, no response. Also, beware the services that supposedly help recover - they're likely scamming the desperate and gullible - I've flagged the comments in this thread. H2Hashes looks very similar in form and style.

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.

DO NOT BUY Scam, my mining packages were confirmed but did not give the supposed btc back to me, plus the $3 I did mine (on a $400 contract) I could not withdrawal.

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.
