If you cash out by bitcoins at a casino and the casino doesn't add enough fees for fast confirmation. If the price of bitcoin drops a lot. Should the casino be held responsible for the price differences in which you cashed out at and the current loss in btc prices?
I think yes but no any casino will be willing to take this responsibility. They only update their system when someone report this issue to them and what best users can do is to either wait for confirmation or use tx accelerator services like viabtc tx accelerator to get faster confirmation.
