Again couple of sites on which you can win skins without doing anything
CS GO Whale - http://g oo.gl/UyfY6n ( remove space in link)
- ( you deposit skins and hope to get something back, but with extra points you got you can withdraw)
CS GO FireWheel - http://g oo.gl/EKHDFq ( remove space in link )
- ( you are just spining wheel and you can enter this code"coinzcoinz" without "" and get 500 points
which is about 0.5 € )
CS GO Click - https://g oo.gl/2reUJP ( remove space in link )
- ( nothing to explain here you just share links )
Again as i said all sites are safe and you can only win stuff
