Hey guys,

i live in a country with a super low electricity cost about 0.004 USD/kwh so electricity cost is not important for me, considering this i am thinking of buying about 10 units of M3s to start mining mainly because of its low price ( i can buy 10 units for 1,600 USD) , but i have one big concern which is the old technology of this miner, i would like to know if i can use this hardware for like 15 to 24 months? as per my calculations its ROI would be about 272 days with increasing hash rate difficulty of 7% per month, considering this do you recommend my plan, i would appreciate if you could challenge me or give me your advice/solutions.

also i have a warehouse to install them so noise is not an issue for me.

needles to say that i am a noob in mining. Grin

thank you in advance.

Hi there Pooya. I have a friend here in my country who is using this model M3. He told me the following:

1. It tends to break the hash rate too often. He showed me data of the miner going from very high rate to very low hash rate.
2. It consumes a lot of power, much more than an Antminer of the same capabilities.

For those 2 reasons I have decided not to buy those. I will keep using Bitmain.

One more thing. One of the official resellers of this Whatsminer brand is the people of Pangolinminer. Recently I tried to do business with them and my experiencia it was very bad so I do not recommend them. Use another reseller or try to contact the manufacturer in CHINA.

PEACE out and BITCOIN ON.
