Put all my balance into Barca and won, and now put all my balance into Liverpool. Judging from how shit Arsenal were and how easy City strolled, I think Everton will be blown away. Pro teams prepare much better during lockdown it seems.
It's a combination of your balance and total wagered as a ratio to total free winnings. So with a small total free winnings $5 would be enough. The balance part of the requirement is capped at $100 so as not to disadvantage old accounts.
Answer came in time, was just beginning to really wonder how much longer I'd be able to hang on to free captcha -- probably very long time, as I'm 3 tiers away from max free bonus (gained from wagering).
