What am I doing wrong?

I think you are under estimating how well you are actually doing. If your up 400 in two months then your doing better than a tenner a week. It comes in gradual. I think it’s a common mistake for beginners to expect easy or quick money.

It’s not like that.

To make more money spend more time, do more offers.

Don’t listen to what everyone else is saying they are making, it’s not always true and some ppl cod themselves about what they actually make, maybe forgetting to record some of the losses. And then others are making lots but their lives are consumed by this hobby. I’m guessing 1-2 hours per day and more on weekends for anyone making £1000+ per month.

You’ll improve your profits with experience. You’ll notice you will get the knack of finding cheaper qualifying losses and bigger free bet extraction as you become more used to the markets and the exchanges. You’ll start getting quicker and that will allow you to do more offers and make more money.

Always keep looking for new bookies, new offers, new methods.
