CS:GO Jackpot Sites offer a fast way to get yourself some nice skins. You have to deposit your own skins and you can win the skins of other players. You can also lose all. Those sites make money through commissions. On every Jackpot that's being played, the site takes a commission between 2% and 10%, the commission is different depending on the site you use. On most sites you need to fill in your tradelink which you can find here.
Don't deposit your playskins if you don't want to lose them! Use sites where you can get a high percentage to win. If you have 1000$, you can go on big sites like CSGOFast.com and try your luck. If you only have some small skins, go on sites like WTFSkins.com and try to win. Check the commissions that the website will take before you start playing on it.
Some sites take high commissions, avoid these websites!
Some scam sites will try to steal your items, don't use them! You should always check, if you are playing on a legit website. If you have any issue getting your items it may be a scam. If it is not, you can try to open a support ticket and explain your problem.
We would recommend using well known sites with many players. For example, we personally like the sites on our list.
