Did you? As nutildah lays out clearly; on May 15, 2018 LiveCoin notices what they suspect to be a DDoS attack on MONA. On June 7, 2018 they decide it's time to stop trading MONA and freeze the asset. Three fucking weeks later?
It doesn't matter, the attackers had already sold fake MONAs on Livecoin until the network of Mona was stopped by team.
