Free CSGO Skins through promo codes

As most sites require a deposit before you can withdraw, it can be smartest to go with a high risk/reward stragegy - which means betting green as an example. Green has a 1/15 chance of getting picked and a 14x return. 14/15*100%=93.3% return on average(you will lose in the long run, should you not have enough coin).
Let us say you use 15 websites with 0.50$ free, and you bet green on each one: 1 of those websites on average(possibly more of them) should return you 7$ of skins. Now, despite the website requiring - let us say a 5$ deposit and full bet - you will still earn 5*0.933+7=11.66 <-> 11.66$-5$=6.66$ profit As many sites only require you to bet 50-75% you can easily approach 7$/15$=0.466$ profit per site.

Martingale is a betting strategy that involves betting an initial value which is nearly guaranteed to be won, you can this way fabricate your own odds more on that later. For now; the stragegy involves betting enough to cover your first and prior bets, we often use the black/red paradigm on the roulette for its simpler way of adding up bets. With green you would have to bet 15/14*last_bet to do martingale, of course you would play more rounds on average, but increase your bet size at a more controlled phase. With red/black you have to double your last bet, your bet increases exponentially: 2^rollswithoutwin-1*initialBetAmount
