In the past, you had to wager the same amount that you were credited once. So if you received 10$ through a survey or a competition, you also had to wager at least 10$ on a game of your choice to be able to withdraw the coins. This is not so difficult with sports betting if you simply bet on results with a 1.01 rate, e.g. in cup games.
I remember when we received our payment directly to our bc.game account and we were required to wager it 1x, I simply just searched for a game that was already playing 2:0 and will soon end with an odd of 1.01 – 1.03 (I can’t recall the exact figure) and wagered 70% on it and the rest I went to play plinko since that was what I would have played if I had funded my account, I ended up losing the remaining one after several hours playing and the 70% was swapped to TRX (due to transaction fee ) and withdrew to my wallet.
If I had wanted to withdraw everything it would have been a walkthrough for me since I’ll still choose a similar odd and wager it before I’ll initiate my withdrawal but I just wanted to leave behind the 30% (I’m not sure if it’s up to though. )
