I do both - sell and win - and it's a win-win for everybody. I get up to a 98% win rate and use my own System as well as selling it to recover some of my playing costs. And since there are hundreds of games that means little competition so I'm happy to share my success formula around the world. What my System does is give you the best chance I know to get multiple wins - which has turned out to have an amazing success rate for me and thousands of Silverites (buyers of my System).
