Wolfbet saw the potential into those memecoins that they have recently adopted and that's because those meme coins have got a huge community and they're backing the coin. And that's why it's wise for them to adopt it so that if there are gamblers who are also holding those memecoins, they're free to deposit and play anytime they wish to. At the same time, during the bull run, many gamblers would like to gamble with their memecoins instead of precious cryptos such as BTC and other top coins.
At least the more you provide many deposit options the better for profit and some big casinos have also implemented the system first. As long as the meme coin that is registered has a community and high market capitalization it is the right decision. Moreover $PEPE is one of the meme coins that ranks 3rd on CMC after Doge and Shiba Inu.
