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!!
This often happens. Of course, updates related to the distribution of prizes may be left behind and this is important, usually there is a time limit that gives both filling out forms related to changing wallet addresses and so on.
