The United States-based computer programmer from Brooklyn has convicted of running a fake initial coin offering (ICO) and has been sentenced to a year and a half behind bars. The crook used to run two scams ICO’s, both of which were advertised as being backed by collateral — diamonds and real estate, respectively — that did not exist. Almost 1,000 investors invested at least $300,000 in the scam ICO during the summer of 2017.
