I'm not blaming the Oikos project. Actually I don't know what was wrong but still I don't receive my Oikos coins. But I did everything right during submission. I submitted the right wallet address as a website link Tron wallet suggested to me. Even admin didn't warn me, if I submitted the wrong wallet. No distribution Bitwings then now Oikos cons!!
Ask the bounty manager what's wrong. If they paid other participants then they should pay you. If they said that they sent you the right amount and you didn't receive then ask them for trx. Sad but true is sometimes managers kept the token and make an excuse. Though it happened so many times.
for oikos I doubt their bounty manager does cheating like that, and I think this is purely the OP's fault because he entered the wrong TRX address and also maybe doesn't use a wallet like tronlink which can read oikos token or using mathwallet, and also what I'm surprised that bounty hunters are now rare monitor bounty channel when it's finished even though incidents like this could happen and usually to make repairs we have to fill in form like in case of bounty cartesy, some people lose their rewards because they are no longer active on bounty group.
