英语百科
Tipster
A tipster is someone who regularly provides information (tips) on the likely outcomes of sporting events.
In the past tips were bartered for and traded but nowadays, thanks largely to the Internet and premium rate telephone lines, they are usually exchanged for money, and many tipsters operate websites. Some of them are free and some require subscription.
