Recently, I have been concerned about scams in cryptocurrency. In particular, I’ve been seeing the term "rug pull" more and more, and it’s really causing a lot of investors trouble.

In simple terms, a rug pull is a scam scheme where the development team raises funds from investors and then suddenly abandons the project and disappears. It’s like participating in a fun game at a party, only for the host to take everyone’s money and vanish just before victory. Since the DeFi market is an unregulated area, these malicious acts continue to happen.

The reason such things occur is because scammers use social media influencers to create hype. When a token gains attention and its price rises, ordinary investors jump in. At that moment, the developers sell off their assets and disappear. By the time investors realize it, the token is almost worthless.

To spot a rug pull, there are several warning signs to watch out for. First, if the development team is unclear or their track record can’t be verified, be cautious. Projects without liquidity lock-up are also risky. Additionally, watch for restrictions on token sales, sudden price swings by a limited number of owners, or promises of unrealistically high yields—these are red flags. Not undergoing external audits is another warning sign.

Looking at actual cases, OneCoin was a scam by “Crypto Queen” Ruja Ignatova, who defrauded billions of dollars worldwide. She fled in 2017 and remains missing. Squid Game was a project inspired by the Netflix drama in 2021; the developers raised funds in a few hours, then cashed out and disappeared. AnubisDAO also collected $60 million, only for liquidity to vanish and the developers to run away—classic rug pull.

The scheme typically involves scammers embedding backdoors in smart contracts, executing “dumping” to rapidly sell and cause losses for other investors, or restricting sell orders so only they can sell. Ultimately, investors are left with tokens that become worthless.

Legally, regulators worldwide are tracking rug pulls as fraud or securities violations. The SEC in the US and the FCA in the UK are actively responding, and those involved can face hefty fines, asset confiscation, or prison sentences. However, due to the decentralized and anonymous nature of cryptocurrency trading, law enforcement’s ability to track these scams remains challenging.

In May 2023, the EU introduced the Markets in Crypto-Assets Regulation (MiCA), the world’s first comprehensive regulation. It is expected to strengthen market oversight and investor protection. As regulations develop across regions, hopefully, these scams will decrease. When investing, it’s really important to be aware of these warning signs and to make cautious decisions.
