Well, the Betkin may have tested the campaign for a week and may not got any benefit or maybe they do not have the sufficient fund to continue as of now and may restart the campaign later. However one thing i do not like about this campaign as they payment was shifted from bitcoin to Trx.
I mean how can you do that ? The campaigns paying in bitcoin get more exposure as they are listed in the services section. While the campaign listed in the altcoin section may get less attention specially when the campaign and project is a new one. So here the participants should have been paid in BTC when they listed it in services section
