I have lost some Bitcoin in the past before and I regret losing them because nobody wants to lose their Bitcoin. Bitcoin can become worth allot of money in the future.
I lost them with gambling so I suggest that you do not spend your Bitcoin on gambling.
I think if you already know the inherent risks in gambling I'm sure you would not do anything stupid to do with all your money gambling or betting a large amount? I'm sure if you already know the possibilities that exist on a gamble you will be ready with all the risks and not afraid of defeat
