USDminer and Muxminer are crypto mining scams that have been discovered recently.
USDminer claims to have been operating since 2016 and currently has more than 36 million registered users. However, the USDminer website was registered on September 23, 2021, so 36 million registered users within three weeks are untrustworthy. Muxminer’s scam is slightly different from a typical cloud mining scam. It claims to sell mining machines and is sponsored by Kraken.
Kraken has confirmed that it has nothing to do with Muxminer and is not a sponsor. At the same time, the sponsor logos that appeared on its homepage included Kraken and Honeywell.
