Why is it mine?
Coins to the bitmesh exchange are not credited for a week!
They say that the reason is fork of the coin. Network is unstable.
The developer does not even appear here.
It's probably a failed transfer, try to do a wallet check.
Your coins are most likely in your wallet. (because of how MimbleWimble works, they might not appear in the UI without unwrapping)
The last message from the developer - April 06, 2019, 09:26:20 PM
Coin is dead
We are more active on twitter, discord, and telegram.
I will try to make more time to respond here, thank you for reminding me
