Yes risk free means you are not using, therefore risking any of your own money.
So this is not risk free as you could lose up to £10. My advice is only advice and some people will disagree but that's ok.
I do a large amount of Casino offers. Low-high risk so I understand the process very well.
My honest advice would be for anyone to do all the sign up offers, build a bank to at least £2k (profit) and then start incorporating (but only if they understand how the offers work and have done all the available no risk casino offers first) low risk, £10 and under casino offers.
Put it this way. My bank is about £7k of pure profit. Until yesterday, for the week of casino offers only, I was £200 down. That isn't even especially uncommon. But I've also made a lot of money from them so It doesn't affect me or make me think 'shit I've lost money' it's all part of the probability.
With a bankroll of less than £1-£2k, losing £30 over a few offers actually makes a big difference.
There is so much money to be made from sign ups and reloads and then betclubs and daily offers. Easily £1k+ a month! Without involving any risk 🙂
