Yeah, I really have to stress I have no idea how any of this works so perhaps a roll-back for everyone that bought the fake MONA coins would work?
Probably not, it's been trading for a year so surely people have bought and sold and bought something else and withdrew etc... I doubt it could be untangled with a rollback. Livecoin really made in unnecessarily complicated by allowing a known bad coin/fork to be traded for so long.
Let's try again: OP bought MONA tokens ONE YEAR AGO. Not one week, not one month. Where he was all this time? For example, i lost 800 dollars in Wagger due to MY FAULT. I'm not crying about "scammers which stole 800 dollars from me".
Everything is very shady in this story.
OP doesn't show proofs of his Livecoin balance (Does he has something except MONA coins on exchanger?)
OP doesn't answer about e-mail (Did he receive e-mail notifications about deposit/withdraw closing)
Most of that doesn't really matter because Livecoin essentially confirmed the OP's story and the biggest problem is how they're handling it (and the forks/attacks). If the OP is shady Livecoin is welcome to present facts to that effect.
