I've been a professional gambler for 5 years now. I've have a proven record of maintaining a 30% ROI for the last 3 years.
I bet with flat stakes so I just post all bets at 5/10 on here.
My bets are fairly mainstream and I personally place a lot of bets through betfair exchange. Normally I have around 25-35 bets a month but over August, September and October, you'll see up to double that.
