Don't mine bitcoin with them!
Hello everyone.
I bought from them Innosilicon T3+57 miner at the end of 2019, paid with bitcoin, they did not provide another option at the time. It cost me about 0.4 btc. Until the end of 2020 the situation was more of less acceptable although performance of the miner was less than in technical specs and daily revenue was consistently less then you can calculate in whattomine.com, for example, considering their service cost 21%. In two years I earned just about 0.1 btc. Considering that the life cycle of the equipment is on average 4 years, I will not even be able to return the money. It was my mistake, it's good that I bought only one miner. Just buy bitcoin guys!
On top of that recently my miner went offline for six days without messages and explanations on their part. When it appeared online I saw reduced hashrate 45 Th/s instead of 56 Th/s. I informed about that Miroslav Ivanov from technical support, he answered that my miner is ok and running on balanced mode and temperature sensor controls hashrate. I know from technical specs that 56 Th/s is reachable only on performance mode and I asked him to switch my miner on that mode as it was always before. He said that it was risky (!?) Long story short, they switched my miner to performance mode and for two days I saw 56Th/s, then hashrate decreased to 39Th/s, they informed me that one hash board is broken, said it was always running on balanced mode (outright lie) and blamed me for decision to switch to performance mode. Amir Ness, founder, refused to talk to me. After bringing this issue up for discussion in telegram group with other customers, they admitted that miner normally was running on performance mode, all hash boards are working and increased the speed to 50 Th/s but left payoffs as for the 39 Th/s. What a sneaky trick! I wrote my indignation in the telegram group again, accused them of cheating and admin kicked me off the group. Stay away from these people, they treat clients badly, hide information.
I can characterize them as semi scam project.
There is a lot of negative information about them on social networks and YouTube. I have proof of everything said in this text. Take care, bye.
