The altcoin markets were on fire for the past 2 months. It's kind of sad there was no 10BTC to 100BTC move by GAM.
Oh but there were days that GAM moved more than 10 BTC and it has already reached over 27k Sat level, so if you invested even 5 BTC in the ICO, that was worth almost 14 BTC at that peak and it will be high in value after enough burn of tokens is reducing total coin supply in a couple months.
