This further cements the Bitconnect site, currency and platform as a Legitimate one. They have done a lot recently and thus is yet another piece of proof that they are taking problems in a responsible manner. Sure it would be nice if the problems didn't arise but sometimes problems have to happen for the security to be sorted. This is why there are continual updates for operating systems.
