for the moment the team HIGH GAIN is in Switzerland for the project, is true that the team does not communicate enormously at the moment, but if it was a scam they will persecute on the marketing to attract a maximum of victims , moreover the scams are more often made by ICO, which gives the possibility to steal a lot of money, if one calculates the marketcap of HIGHGAIN at this moment that gives: 9.09 BTC (82 724 900 HIGH x 11 SATOCHIS), knowing that the majority of HIGH are from airdrop, not very good for thieves lol 
if HIGH GAIN is a scam, then it was really a bad scam, by a bad thief without motivation
