There are a few scams out there, and there are a few real deals that are just shit punters.
I can honestly say I tried with a few sport betting groups who lead me know where.
Marks system is pretty fool proof, you work units (stake size) proportional to your bankroll and build up from there.
The main sheet we use for our day to day bets racks in between 120-200 units of profit a month. So $10 units would get you $1200-2000 a month.
That's what you get for $200 a month. If you bet in $20 units that would double. $100 units you'd be looking at $12000-20000 a month.
I'm slowly building up as I've taken about $5000 out for my new car. There is also an extra's and exotics sheet which some of us use and have to pay 25% commission.
This makes up the other 50-60% of my income.
Honestly, if you don't believe. See these comprehensive list of results.
There are around 20-30 members so that we don't overfill the tote pools.
We closed up spots at the end of last month.
