You’ll pretty much need mostly Twitter and Telegram. You’ll find out about all sorts of shitcoins over there. There’s a bigger underlaying issue though - you’ll need to spend a ton of time to find out about new coins and separate the good from the bad ones. Memecoins are like gambling, only very few succeed and even that’s mostly temporary. For now, the only truly successful memecoin is Doge. The others need to pass the test of time which, frankly, is pretty harsh and hard to pass. I expect most memecoins to be gone in a matter of months or years. New ones will come up, the previous gones will go.
