I think I can't agree on this. How is that kind of setting booming if most of the people don't even like to try any of those? Most of these blockchain gambling only accepts specific crypto(altcoin) that they support and that's what makes it a hassle for most users.
Instead of adopting the most accepted like bitcoin and other popular altcoins, there's already a choice that has been made by the devs of these platforms which isn't really clicking.
