I don't think those meme coins are good for investors but if you are gamblers, you can buy them and make your bet. Just don't sell your house, borrow money to buy meme coins.
It is good for exchanges and casinos to list meme coins as I believe if one is a gambler, he possibly has meme coins in portfolio and will be ready to use those meme coins on casinos.
I don't care if the coin is a MEME or any other if i am to gamble it on a casino. Gambling is altogether a different thing than trading. For trader, you need to know if this is a MEME coin and risk involved with the coins.
For a gambler, if he holds a Meme coin like PEPE, it gives an easy way to deposit them to the gambling casino if the casino supports it.
Also since there is an hype of PEPE, Rollbit offering PEPE deposit may attract many new gamblers to the site.
