Telling the end user to contact the developers of Mona and Monero doesn't lend any help to Livecoin's situation either. I believe many exchanges/developers/wallets work together to solve bugs/problems/attacks with various coins. Not sure if it is a language thing or that Livecoin believes it is solely the developers fault and that they need to be 100 percent compensated but something is majorly wrong if they can not open a channel with the developers when coins like Monero are being actively traded, and safely at that for quite awhile since the bugs/attacks.
My understanding is that Livecoin expected them to orchestrate some sort of bailout/rollback fork to reverse their losses. The Monacoin developers refused, which is a perfectly respectable position for developers of a POW protocol. An impasse was reached and Livecoin never did anything to rectify the issue and compensate their customers.
Same with Monero. Livecoin simply expects the Monero developers to pay them $1.8 million to reimburse their losses. Legally, the developers have no liability. It's right in their software license! On the other hand, Livecoin is legally liable for the deposits its customers made and now won't pay out.
The way Livecoin is acting, you really have to wonder how deeply insolvent they might be.
