In Thailand, SEC bans meme- and fan-based tokens from digital exchanges.
With all the new coins emerging, how can you tell that it’s a shitcoin?
Easy. If it’s not Bitcoin 
It’s all about your own DD, due diligence. Don’t depend on Twitter or Reddit to make decisions for you. Research on your own, review the use cases, research the team, following along with the development roadmap (they have one, right??!?). Sit it on an AMA or Discord/Telegram chat. That should get you started.
I avoid any crypto that is not a top tier crypto.
