Five different csgo match betting sites is good, I didnt know about all of these and I think there is a few more on top of that as well. More then I thought total, I might give them a go as I have plenty of skins anyhow.
The CSGO major is to happen during January and my old favourite site went into inactivity unfortunately.
I'm actually in contact with a relatively new betting site that is now accepting bitcoin & skin deposits. Should be a very exciting addition to the esports list. More updates to come.
