BitMart users say founder blocked appeals over 800,000 ATEG in wind-down

Users of the wind-down exchange BitMart say founder Sheldon Xia blocked them on X after they asked for access to roughly 800,000 ATEG tokens and other funds held on the platform. Aliyu Almustapha, who signed an earlier appeal on behalf of ATEG holders, is among those raising the complaint. The dispute adds to concerns about how exchanges handle customer assets during shutdowns, a recurring risk for holders of small-cap tokens.
