Livecoin Crypto Exchange Suffered Loss Of XMR
According to a recent report, Livecoin crypto exchange suffered a significant loss. The exchange claimed it lost 15108 XMR worth $1.8 million. The exchange noted some inappropriate transactions on July 20, 2018, after which they confirmed the loss.

Livecoin expresses its dismay that Monero developers did not inform them about the risks or the need to limit Monero transactions. Now, they have halted XMR transactions for an indefinite time, probably until further negotiations between the exchange and Monero developers.

Hello
A vulnerability have been detected in this asset software. In course of negotiations, the developers refused to take responsibility for their software, that is why deposit and withdrawal of this coin have been suspended. If you have difficulties with this asset, or you have questions about the time when it will be enabled again, please, address the developer, because it depends entirely on the developer.


Monero has been on maintenance for months, and no news when they will bring back online the wallet, also other coins that are forks of Monero are on maintenance, like SFT and SFX.

It seems that all Monero forks coin got attacked on Livecoin, my advice is to get rid of all the Monero and Monero forks you hold on livecoin, sell them for BTC and withdraw from there as soon as possible.
