Well if your going to gamble especially with your amount. I would reccomend CSGOLounge as its less risky if you research but less money to be made. Basically 2 teams play eachother if your team wins you get your skin that you bet + winnings. Your winnings can be like 10c or like $800 depending on what and who you bet on. Also if you win you WILL do it again especially on lounge.
For research you can check: r/csgobetting, HLTV the players steam accounts, previous matches, how the preform on the map. Could also join betting group but they are cancer
Other sites like CSGOBig are more risky but you can lucky. I would not reccomend.>>648355555
