last time i hear about satoshidice about 3 or 4 years ago.
and now they fully BCH bet. no wonder,considering btc have a slow transaction speed,people must be boring to wait it.
The reason they moved to BCH instead of BTC is not just the speed, it is probably siding with the miners which tells us that maybe the new owners have a mining operation as well. If you want to keep the waiting time to minimum you could easily just pick up off-chain and you can continue to exist just like all many other dice websites.
There is really no on-chain dice website that I know that made it big since the off-chain system started to work, it was first just-dice if I am not wrong that started the off-chain and with that we started an era of people just putting their money into the casino and gamble and whenever they feel like they had enough they withdrew their money.
Unfortunately, satoshidice just didn't care and didn't want to work on it and just wanted to reep profits and they got in at the very wrong time when they bought the website.
