I've spent hours on Alibaba asking sellers about Mininers and looking for websites, without any real progress. This sector is full of moneygrabbers and lying people, read many bad reviews about shops not delivering or faulty equipment. The prices are too high and the machines are lied about their specs or they send old used miners when they upgrade their machines resulting in faulty items. "Sellers" don't have stock. I'd be surprised to find an honest shipping website, they don't exist.
As professional buyer, I don't think they are going to buying miner from Alibaba, specially for some high number miner.
Also most of those seller from Alibaba is not professional on cryptocurrency area, they are just young girl only speaking english.
We have own hosting farm and real first hand miner in hand, we also specify is Miner if are used on store clearly to avoid any mistakes.
We looking for long term cooperation.
