The (Defi) and cryptocurrency industry has witnessed its fair share of scammers, seeing that over $2B was lost from rug pull events in 2021, according to data tracker Chainalysis. Out of all crypto scams that took place that year that totaled $7.7B, rug pulls accounted for almost 40%. The scamming event takes place when a virtual asset developer manipulates a token's worth, making it look more lucrative than it is. After that, the developer abandons the project, taking investor funds with them. decentralized finance However, crypto enthusiasts can avoid the occurrence of rug pulls, but it could be harder than many think. Crypto veterans often encourage people to DYOR(do your research), but what exactly does that mean, and what should one do to avoid getting scammed? How a Rug Pull Happens A developer creates a cryptocurrency or Defi project and makes it appear very lucrative to investors. Once investors have allocated enough capital to the project, the developer may cash out and abandon the project. Generally, rug pull projects are those crypto projects whose developers have put little effort into them. They are operated by people whose primary goal is to defraud investors of their money. They could accomplish their plans within days or months, depending on how well planned the scam architecture is manufactured. Additionally, the assets within these projects may look slightly similar to other cryptocurrencies within the market. Different types of Rug Pull Liquidity Stealing To make a cryptocurrency tradeable, developers need to create a liquidity pool that holds an amount of the currency to allow investors to buy and sell. Judging from most rug pull events, the developer brings about a liquidity pool, where investors can lock the project’s newly minted token and another legitimate cryptocurrency, we could say Ether. As the scam crypto's value increases, investors start buying in the asset, exchanging it with their ETH, which remains locked up in the liquidity pool for a defined period. Investors then continue buying the token, which could help it increase in value. Subsequently, more ETH is poured into the liquidity pool. At the time of the choosing, the malicious developer will pull the ETH from the liquidity pool, leaving just the worthless token instead. Investors cannot trade back their now-worthless tokens while the developer takes his money in legit ETH and makes a run for it. Disabling the ability to sell tokens The result of this scam is almost the same as liquidity stealing, but the process is different. In this scam, the developer adds a bit of code that will make investors unable to sell their coins back to the exchange. Investors can buy the scam coin, but only the developer can sell his coins because of the fraudulent piece of code. As the price rises to the point where people start trying to cash in to sell their coins, they realize they can't sell the asset. At some point, the scammer will deem the price high enough, and he will sell all his scam tokens, running away with the value of the investments that had been poured into it. Developers cashing out The cash-out doesn't sound like a scam in a free market, but it qualifies as one of the projects is created for this sole purpose. Like the previous two scams, the malicious developer starts a project with an overblown value proposition. The promise usually involves a token feature or platform in development and will be released soon. But in reality, the developer mints or creates a worthless token, giving himself a large part of these tokens from the beginning or buying them in the market at a low cost. As the promise of the revolutionary product makes investors buy the worthless tokens and the price goes up, the developer cashes out all his shares. He can do this all at once or over time, so the rug pull isn't as obvious. Either way, investors will be left with the worthless token while seeing their investment funds erased.
