Why Online Casinos Business is Success???

I’m interested about the online casinos method to involve many players worldwide and trying to looks the history of online casinos. As usual, I use Google to find out something on the internet. From some site I know that Casinos games that can be played through the internet are started since 1995.

According to the researches that do by British and American consulting agencies, the total volume of money spent in online poker in 2007 was $15,000,000,000 and from that amount, they research find that 13 million of UK population and 50 million of the US population play poker. Wow… That’s a huge amount. That’s why many USA online casinos we can found on the internet.

So, why online casinos business is success? Well, I have my simple opinion about this:

1. Because we don’t need much money to play Online casinos. This is the main strength of Online Casinos. The opposite matters if we want to play casino games off line like in Las Vegas that need much money to spend.
2. Because online casinos offers many and huge bonuses. We can’t find it in off line casinos.
3. Because the opportunity to earn money or winning some money from online casinos is have same probability with off line casinos

I think those three reasons is the key of online casinos business is success. Any comments guys?
