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?
No.
they don't care i think but i know for sure that these service like exchange and casino have special deals with miners and they can have fast confirmations with very low fee -snip-
No, they don't make special deals with miners
then how you explain that bittrex have 20k satoshi fee all the times, when i withdrawal my coins from them? 20k satoshi is way below the average and shoudl remain stuck forever instead i always get my coins very fast from them, the only explanation is that they are miners themselves, or they do the same thign as viabitcoin the accelerator
