There are several types of scams in the crypto world. Here are the most common ones:

Ponzi and Pyramid Schemes: These scams promise investors high returns. New investors’ money is used to pay off old investors. However, if new investors cannot be found, the system crashes.

Pump and Dump Schemes: Scammers buy a low-value cryptocurrency in bulk to artificially increase its price (“pump”). When the price goes up, they sell the coin (“dump”) to make a profit, but other investors lose money.

Fake Exchanges: Scammers create fake exchange sites that look like real exchanges. When investors deposit money, the scammers take the funds and run.

Fake ICOs (Initial Coin Offerings): Fake ICOs, which are presented as a new cryptocurrency or token project, raise money from investors, but the projects do not actually exist and the scammers run away with the money.

Phishing: A type of scam that attempts to steal users' private keys or wallet information via fake emails, websites, or social media messages.

Airdrop Scams: Users are promised free tokens in order to obtain personal information, private keys, or login information.

Rug Pull: In this scam, developers disappear after releasing the project, draining their liquidity pools, leaving investors with worthless tokens.

Social Media Scams: Users are asked to send cryptocurrency by imitating the accounts of celebrities or well-known people. The promise is that they will be returned several times the amount they sent, but this is a complete lie.
