Many projects add more and more crypto on which investors could buy their tokens.
What about you? Do you accept any other crypto, except eth? May be even fiat?
They also accept btc and ltc just from the beginning as i remember.
Popularity of that three is really huge, so there is no need to add more
But many people who are interested in gambling have nothing to do with crypto world, why there is no opportunity to invest with fiat?
