IOTA was chosen because the combination of the tangle and flash channels will enable us to offer almost instantaneous fee-less transactions, be that micro-transactions or larger ones.
There are plans in the future to accept other crypto currencies as well, but in the beginning only gambling with IOTA will be available.
ok, sounds interesting enough, but I am on Coinbase, and I doubt that I will go to an exchange to buy Iota just for this thing.
That's the initial hurdle that they will face here.
For all the gamers that would find it difficult to get Iota just to join this platform.
Maybe the team can have iota available within their app and the user can just buy using their btc, eth, or any other famous cryptocurrency they have.
