Lets say they want to relaunch the giveaway, they should ask user to post btc address or simply ask users to post their username in the casino but the reward should also be in a form of btc.
Let's suppose they want to give the giveaway in USDT (or altcoins), so what can be the options for them ? Will the altcoin section will survive this purpose ?
Nice! That's a pretty good plan to make on-chain games as accessible as much as possible. Plus, ARB and POL are good picks IMO as they tick all the boxes of stuff cheap fees and people's general familiarity. Because these two are known in the space + we can use wallets and exchanges (if need be) crypto folks are likely to be familiar with such as metamask, peeps are less likely to be cautious and it'll lessen the learning curve as well.
Well, the more coins a casino support, the better it is but i haven't use ARB, POL or any such altcoins for gambling. Most people just love to gamble with traditional coins like Dogecoin, TRX, USDT and bitcoin too in some cases. If they can directly integrate the casino with wallets like Metamask etc, that will be a good step in decentralzaion.
