I am thinking about opening an account at tradesports. I currently use matchbook almost exclusively. The only problem I have with matchbook is that it doesn't carry all the events that I am interested in. I see that tradesports have a C+ on SBR. What are the main problems with this exchange? Is my money safe there? What kind of signup bonus does it offer? I see a first 50 trade commission free and a $25 bonus through a Google search. Thanks for your help.
