The fact that KYC-free exchanges have become such a trend is actually for a reason. There’s something I’m often asked about these days, so I decided to sort it out again.

First, the basics. A KYC-free exchange refers to a platform that requires no troublesome procedures at all, such as submitting identity documents or verifying your address. Uniswap and PancakeSwap are representative examples—especially Uniswap, which, as of August 2024, has 12 million monthly active users and a 60% market share. PancakeSwap also has 1.9 million unique users. Why are they used so widely?

For people who place a high value on privacy, “KYC-free” is truly appealing. In today’s world where data breaches are commonplace, being able to trade crypto assets without disclosing your identity is a major advantage. Also, it’s simply easier to access—you don’t have to wait through long verification processes, and you can start trading right away. For people in countries where crypto trading is banned, and for those who can’t access the traditional financial system, KYC-free exchanges have become truly important infrastructure.

However, this is the important part. Let’s talk about the risks. Because it’s KYC-free, scammers are also easier to attract, and security concerns are significant. Even if something goes wrong with the code, there’s no company that can be held accountable, so users can hardly get any support. And regulators around the world are monitoring these types of exchanges, so there’s also the risk that individuals can be identified through blockchain analysis.

There are also many limitations on the functionality side. On platforms like Uniswap, you can’t withdraw fiat currency, and if you deal with assets that have low liquidity, the trading pairs are restricted. As of November 2023, the assets deposited in DeFi total about $50 billion, but the risk grows accordingly.

Decentralization is an ideal mechanism for protecting privacy and freedom, but at the same time it also has the potential to become a breeding ground for illegal activities. Since there’s no central administrator, even if scams or money laundering occur, there’s no one to complain to. In fact, a darknet marketplace called Hydra combined a KYC-free decentralized exchange with a bitCoin mixer to launder crypto assets worth several million dollars. Because transactions are anonymous and spread across multiple blockchains, it’s hard for law enforcement to trace the flow of funds.

The case of Tornado Cash is also symbolic. It was used to launder more than $600 million worth of Ethereum stolen by a North Korean hacker group. By making deposits and withdrawals through multiple smart contracts, it completely breaks the link between sender and receiver. In 2023, the US’s IC3 reported that there were over 60,000 complaints about crypto-related scams, with estimated losses reaching $5.6 billion.

When using a KYC-free exchange, taking steps to protect yourself is essential. Strong passwords, two-factor authentication, VPNs, moving funds to a hardware wallet, and staying alert to phishing scams. If you don’t take these seriously, since you can’t rely on a central institution, all the losses are ultimately on you.

Banks have deposit insurance, but KYC-free exchanges don’t have such protection. Some exchanges may offer insurance against hacking, but the coverage is limited. Regulators are also strengthening crackdowns on decentralized platforms, so users may be exposed to risks such as legal action and asset freezes.

So, in short: KYC-free exchanges give you privacy and convenience, but you have to carry all the security and legal risks yourself. You need to judge with a clear understanding of the pros and cons, and make decisions on your own responsibility.
