[Compilation] Betting, gambling and trading sites

[Willy]

As most of you know there's a ton of sites out there to bet on matches or gamble your skins on, wouldn't it be neat with a compilation of them?
This way people can discover new fun ways to burn their money and skins!

Preferred format:

Site: (Name and link to site)
Type: (Is it a jackpot site? Betting? Trading)
Skins/Real money: (Can you use skins or real money here?)
Short comment: (Could be your experience with the site and possibly a rating)

Real example:

Site: CSGO-Lounge
Type: Betting and trading
Skins/Real money: Only skins
Short comment: 9/10, probably the best betting site for cs:go matches right now.
The only problem is that the bots used to insert skins into the system may be down, but if you donate that's no problem.

Site: SkinArena
Type: Betting
Skins/Real money: Skins only, payout in skins too
Short comment: Great experience. Live chat on the front page for users to chat about the (sometimes) outrageous payouts for tiny bets. I.e. a $5 bet can net you a win of $2000.

Short comment: Never used this one myself, just saw that phantoml0rd posted his winnings from it on FB so it should be legit.
