Good thinking on the part of the team to extend their ICO. It would be very difficult to reach hardcap with a bear market like this considering how huge of a drop BTC and ETH has sustained.
It's no surprise. The team and company behind Ironx is a solid and experienced team. They are able to keep up with the ever-changing market.
Going to that decision in extending the sale is not easy for a project since they already have a road map to follow. The good thing with IronX is they have a good marketing team to make this happen.
