All the different countries and regions around the world have their own laws and regulations when it comes to online betting. Betting is legal in the UK for example, but illegal in the US, but not on a state level. Some states are opening up for online gambling, but this brings aboard a whole nother set of problems. The same goes for a region like India where the laws are still unclear and some regions allow it while others don't.
What is clear though is that depositing and withdrawing funds from betting sites online can be a hassle depending on where you are from. Using your credit card(s) is quite easy, but sometimes there are fees attached to this and not everyone is comfortable giving out this information to websites. That is why we recommend to use ewallets. These are forms of internet bank accounts (or ewallets) that function just like a normal bank account, but they are operated purely online. The big advantage with these is that they are swift in depositing and withdrawals and have low to none fees associated with them. Makes life as a bettor a lot easier.

If everything else seems to fail and you are unable to deposit funds you can always ask the customer service at the site you are trying to deposit at for help, they will usually know best what could be the issue and which option would be the best for your situation.
