Sounds like you're selling these domain names. I don't think it's more effective to buy domains when in fact, we can really think and make our own domains for our betting sites. However, these domain names are attractive though I don't see that it would be an advantage to have these.
There are things that we have to consider, it should sound like its functions and services.
The best thing business owners could do to their business is to acquire good premium domain names. Without it, it will be difficult to break even on the internet. Domain is much more than internet address, it is a brand equity, and source of credibility. A good short premium domain name is much easier to gain credibility with, than a crappy meaningless long domain.
