I think koinomo looks more suitable than neoxcard (this is just my opinion though) mainly because the reward is already in the hands of the bm which means there is very little chance the team will refuse or stall payment like what LunaLand is currently doing to hunters,
and also Jax am currently promoting is another good bounty, price at pancakeswap is already above $2 and the team are building a solid project, things will be more clearer when they migrate to mainnet in Q3 hopefully.
