Bitcoin has become nearly unusable yesterday when it hit over 200000 unconfirmed transactions.
I suggest Megadice considers an altcoin like ETH or LTC as soon as the Lightning network is enabled.
Both ETH and LTC have faster TX and can be traded for fiat currency.
Yes pretty much everybody is angry in this situation because not every BTC gambling website wants to go thru major re-coding to add another alt-coin. And maybe sites will start losing gamblers to sites which have more currencies other than BTC.
I think most people usually keep their BTC in cold storage, send it to the gambling sites to gamble for a few hours and withdraw at the end of the day.
But with these huge fees many will stop completely using BTC to gamble and use alts.
