In May of 2019, Engadget's Benjamin Plackett published a piece titled "The Bitcoin ponzi that won't go away"
According to Plackett, Usi Tech was not only a Ponzi scheme, but continued to operate under different names even after the initial ban by authorities. Two of these names are Eyeline Tech and later WealthBoss.

We recommend you take any investment that promises more than 3% per month with suspicion.
If you monitor the financial markets you'll know that US Treasury yields are lower than 3% per year. Treasuries are a very safe and conservative investment instrument, but they serve as a reference for a bottom line yield. Any investment that promises one year of Treasury yield per week, or sometimes even less, is very likely to be a scam.
Usi Tech customers were initially promised 1% per day, with a minimum period of 140 days. This is an outrageous yield that no legit financial instrument is able to deliver.
At the time of this writing former Usi Tech customers had not yet recovered any part of their losses.
