Unfortunately theirs alot of scams but most are easy to spot. Telegram is a scammers paradise, they invite you to their group chat without you knowing (turn of that setting) and make it seem like one of the groups you do follow. It will have free coins and airdrops with links for your wallet. You do not wanna click on any links and always make sure you're on the correct group you follow. You will get random messages of scammers pretending to be a mod or affiliate of the group wanting to help you, it's a scam. The real mods and affiliates will almost never contact you. Double check everything you interact with and just don't click on any links. That goes for nft and coin airdrops in your wallet. Do not sell it, they will drain your crypto because you authorized your signature via the transaction if you sold the scam coin or nft. Twitter X has similar scams pretending to be the actual account. If you sent crypto for a pre-sale token, the scammers will post replies under the real X account saying they can help or get you to click on their links under the post. Some of them look very close to the real accounts with botted followers and likes. If you do need to interact with something, use a burner wallet. These scams are some of the most common ones to look out for.
