Thanks I visited it now, I will also include the link here just in case some users wanted to look at it they don't need to go and search it https://medium.com/@bitcarra/what-is-single-crash-dual-crash-1c7c1f775c3f

So it was similar to baccarat I thought at first that I need to place bets on each of the dual crash and now I understand how it works. Thank you
