I'm not trying to attack you, I'm trying to understand.
Are you claiming that LiveCoin owes you 0.3
BTC because that is what you paid for a coin that later dropped significantly in value? I understand if the wallet got locked and you could not withdraw/deposit MONA but you could have sold it to
BTC at that point, no?
I have no idea what MONA is or what it's value has been, but help me understand please

The OP is claiming to have bought Mona coins for about 40K sats each. If he was allowed to withdraw his Mona coins, he could sell his Mona coins for 20K sats for a 50% loss.(BTC wise) His only option now, if Livecoin reactivates his account, is to sell them for about 4300 sats each on Livecoin. That is almost a 90% loss.(BTC wise) If Livecoin invoked the option to make all current Mona asset holders take a haircut, the OP will probably still be better off, since withdrawals will be re-enabled, which is likely to have a positive effect on the market price at Livecoin, and if not, he can dump elsewhere.
