Platform Review P2P Marketplace
Buff163
NetEase's giant Chinese marketplace remains the global price reference for CS2 skins, but it is functionally closed to non-Chinese users: registration needs a Chinese phone number and real-name ID, cash-out runs through Alipay or WeChat Pay only, and US numbers were blocked in 2025. Its 2.6★ Trustpilot (95 reviews) mostly reflects locked-out Western users.

What is Buff163?
Buff163 is NetEase's skin marketplace, and for years it has been the price reference the entire CS2 economy quietly runs on. When traders on other platforms argue about what a skin is 'really' worth, the number they reach for is almost always the Buff price. It holds the deepest liquidity in the world, charges a very low 2.5% seller fee, and sits at the center of Chinese skin trading — which is the largest single market for CS2 items anywhere.
Here is the part that reframes everything for most readers of this page: Buff163 is functionally closed to non-Chinese users. Registration requires a Chinese phone number and a Chinese real-name identity verification. Cashing out runs exclusively through Alipay or WeChat Pay, both of which are tied to Chinese bank infrastructure. And in 2025, US phone numbers were blocked from the platform outright. If you are trading from North America, Europe, or most of the rest of the world, Buff163 is not a marketplace you can realistically sign up for and use — it is a price chart you look at, not a store you shop in.
That gap between reputation and access explains Buff163's unusual Trustpilot profile: a 2.6-star rating across just 95 reviews (checked July 13, 2026). That score is not a verdict on the platform's core business, which is enormous and works fine for its intended Chinese audience. It largely reflects frustrated Western users who tried to register, deposit, or withdraw and found the doors closed to them. Read the score as 'locked out,' not 'scam.'
Buff163 fees explained
Buff163's seller fee is 2.5%, one of the lowest anywhere in CS2 trading and part of why its prices tend to be keener than Western marketplaces. On raw commission, it competes with CSFloat's 2% and undercuts almost everyone else.
But the fee is close to academic for most readers, because you have to be able to fund and cash out an account to benefit from it, and that is exactly where Buff163 is inaccessible outside China. A 2.5% fee you cannot actually reach is not a saving — it is the reason Buff prices look cheap on the chart while remaining out of reach at the checkout.
Payments & cash-out on Buff163
Cash-out on Buff163 is where the wall is highest. Withdrawals are processed only through Alipay or WeChat Pay, China's two dominant payment networks, both of which require a Chinese bank account and identity to operate meaningfully. There is no bank-transfer route for a European IBAN, no PayPal, no crypto rail aimed at international users. For a Western trader, there is effectively no way to get money out.
The registration barrier compounds it: a Chinese phone number and real-name ID are needed just to create a usable account, and US phone numbers were blocked in 2025. Some non-Chinese traders historically worked around this through third-party middleman services that hold a Buff balance on their behalf, but that introduces counterparty risk, extra cost, and no protection if anything goes wrong — it is not something this page can recommend.
For context, the whole market now operates under Valve's July 15, 2025 Trade Protection rules, which made delivered trades reversible for seven days and forced settlement holds across every platform. Buff163's access problems for Western users, though, predate and sit entirely apart from that change — the barrier is jurisdictional, not a trade-timing quirk.
Pros
- Deepest liquidity in the world
- Very low 2.5% seller fee
- Prices anchor the entire market
Cons
- Effectively inaccessible without a Chinese phone + ID
- Cash-out via Alipay/WeChat only
- US phone numbers blocked in 2025
Who Buff163 is for
- Traders based in China with a local phone number, real-name ID, and an Alipay or WeChat Pay account
- Anyone who wants to read the global reference price for a skin, even if they cannot buy on the platform
- High-volume sellers inside the Chinese market who benefit from the 2.5% fee and unmatched liquidity
Who should skip it
- You are a Western trader without a Chinese phone number and real-name ID — you cannot realistically register or cash out
- You need a bank-transfer, PayPal, or crypto payout route — Buff offers only Alipay and WeChat Pay
- You are in the US, where phone numbers were blocked from the platform in 2025
The Verdict
Buff163 is simultaneously the most important marketplace in CS2 and, for most people reading this, the one you cannot use. Its 2.5% fee, world-leading liquidity, and status as the global price reference are all genuine — but they are gated behind a Chinese phone number, real-name ID, and Alipay or WeChat Pay cash-out that make the platform effectively inaccessible outside China. The 2.6-star Trustpilot rating is best understood as the sound of locked-out Western users, not a judgment on the underlying service.
Use Buff163 the way the rest of the trading world does: as the price chart you check before you buy or sell somewhere you can actually transact. For Western traders who want comparable low fees on a platform they can genuinely use, CSFloat (2% seller, bank or USDC payouts) is the closest equivalent, with Skinport the deepest accessible option and SkinBaron the cleanest regulated route in the EU.

Buff163 FAQ
- Can I use Buff163 outside China?
- Not realistically. Registration requires a Chinese phone number and real-name ID verification, cash-out runs only through Alipay or WeChat Pay, and US phone numbers were blocked in 2025. For traders outside China, Buff163 works as a price reference but not as a marketplace you can actually fund and withdraw from.
- Is Buff163 legit and safe?
- Yes — Buff163 is operated by NetEase, one of China's largest technology companies, and is the biggest, most-referenced skin marketplace in the world. Its low 2.6-star Trustpilot score (95 reviews, checked July 13, 2026) mainly reflects Western users locked out by the Chinese phone and ID requirements, not fraud against its intended Chinese audience.
- What are Buff163's fees?
- Buff163 charges sellers 2.5%, among the lowest fees in CS2 trading and one reason its prices tend to sit below Western marketplaces. The catch is access, not cost: you need a China-based account to benefit from that fee at all.
- Why do traders quote Buff163 prices?
- Because Buff163 holds the deepest liquidity in the world, its prices function as the market's reference point. Traders on Western platforms routinely check the Buff price to gauge a skin's true value before buying or selling elsewhere, even when they cannot transact on Buff themselves.
- What is the best Buff163 alternative for Western traders?
- CSFloat is the closest match on price, with a 2% seller fee and real bank or USDC payouts. Skinport offers the deepest accessible Western liquidity with free bank-transfer cash-out, and SkinBaron is the cleanest regulated option for EU sellers. All three are fully usable without a Chinese account.
