At the moment all my winnings go back into my float to help that grow so I can take on more and more offers (I've had to pass up on some purely because my bankroll isn't big enough to support them). All that will help my money grow even further, it's like compound interest.
Talking of interest, I would've had to invest £500,000 in an ISA to match the £285 I made in three weeks. Half a million pounds in the bank is worth less than my growing bankroll is when invested wisely through matched betting and advantage play betting! I don't have half a million pounds, not even close(!), but I will continue to beat the interest rate and on top of that, everything I earn is tax free, minimal risk and actually fun as well. Beating the bookies isn't supposed to be possible, so every win is really enjoyable!
So in closing, if you've stumbled here looking for a way to make money, then you're in the right place.
