I dont intend to keep BTC on a gambling platform for ages. But tell me, how often you see people people deposit>gamble>withdraw their funds? Usually they make a deposit and keep it on a platform until they win enough or lose. I think a lot just keep their funds there until they win the amount they have set as a goal.
I can't see them because I do not have spyware installed on anyone's pc or mobile gadget to track down their activity. I am just stating scenario that I always do whenever I am playing in any gambling platform. I know many people keep their funds in the casino but I don't.
Just echoing the thing dimonstration stated. What you are saying is good when the market appreciate but if the market depreciates? I believe you will be thankful that Duelbits had preserved the deposit value of your coins. Just for example, if you deposit 1 BTC during the ATH, and you left it there untouched, and you decided to play now, wouldn't it a good relief that the deposit value is preserved?
