You can kinda "go infinite" using market + double or nothing if your odds are over 63%.
Use the market to "stock" 50% of your money, then play DoN, sell your stock, then start again. The growth is exponential and is really much faster when your odds progress! At 67% you'd gain 60% every twelve cycles; at 75% you'd gain 380% every twelve cycles!
