Hi. There was no ICO or IEO. Even here they did things differently. Their sale was in BTC, but only used as collateral. So if you have bought in the sale period, which lasted few days, you would have get your BTC back in a timeframe of 24 months, every month. They call this Xstakes.
So basically free coins. There were 7 successful xstake distribution till now, so the btc is clearly going back to users that participated in the "sale".
Glad you liked it. Don't forget to join the social media accounts to research more or you can ask me more questions whenever you like.
