It would be nice to bet without risking and investing your own money. You could try your luck with different betting systems and strategies. But is it really possible?
To get yourself free betting capital you can use bonus promotions and free bets offered by bookies. But downside to this is that you still need to deposit your own money to receive bonus and that means you will risk it too.
Of course it's possible to find free bets with no deposit requirements. But these are very small - around $1. And what $1 is worth? That's right, nothing! Minimal stake in most bookies is $0.5 or $1, that means you lose two times in a row and your "Bank" is gone. Everyone will understand that betting with $1 is not serious!
So we need to return to the first option - free bets and bonuses with deposit requirement. Actually it's possible to safely extract these promotions with betting system called Matched Betting. You can find more about it by following link below in a resource box. It will eliminate any risk to lose money. By using this system it's possible to clear many bonuses and free bets and in that way you can build yourself a betting capital without risking to lose anything. For example, you deposit $50 in a bookmaker and they give you $50 bonus. You use matched betting system and extract it safely. Now you have $50 to bet with. Original deposited money is available for withdraw at any time after promotion is cleared. You can extract multiple bonuses and build yourself even bigger betting bank.
This is the only way to get real starting bank for online betting. Maybe you can find some bookmakers which will offer you to punt with play or some pseudo money. But betting without real money is like having sex with rubber doll.
