Buff (also known as Buff163) is an online marketplace where gamers buy and sell skins for games like CS2, Dota 2, Rust, and TF2. It’s owned by NetEase, a big tech company in China, and has been running since 2018. Think of it like a giant digital flea market for game items, with millions of listings and prices often lower than Steam. You link your Steam account, list your skins, or browse for deals. While Buff is legit and trusted by many, it can be tricky for non-Chinese users because of payment methods and account verification requirements.

When we say “Buff,” we’re talking about Buff163 (buff.163.com)—a peer-to-peer (P2P) marketplace for trading skins and items from games like CS2, Dota 2, Rust, and TF2. Founded on August 17, 2018, it’s owned by NetEase, Inc., a well-known tech giant based in Hangzhou, China

This platform has grown into a massive hub, often influencing how gamers value their skins—what traders casually call “BUFF prices.” You can browse millions of listings, enjoy low seller fees, and access fast trades (at least for Chinese users). But there are some important quirks—especially for folks living outside China.

Legitimacy and Trustworthiness

2.1. Buff Is Legit

Buff163 is indeed legit—there’s no doubt about that. It’s backed by NetEase, has been operating stably since 2018, and handles items worth hundreds of millions of dollars.

Plus, review sites confirm its legitimacy. Pricempire calls it a legitimate marketplace with high liquidity and integration with Steam

2.2. Trust Scores and User Reviews

• Scamadviser gives Buff a 62% trust rating, suggesting it’s probably not a scam, though it’s a medium-low risk Pricempire.com+6ScamAdviser+6EsportFire+6.
• On Trustpilot, it averages 2.2 out of 5 stars based on 78 user reviews Trustpilot+2ScamAdviser+2.
  • Many positive reviews praise low prices and wide item choices.
  • But several negative ones complain about complex registration, limited foreign access, and stubborn support.

How It Works: P2P in Action

Let’s take a peek under the hood to see how Buff’s module rolls.

3.1. Peer-to-Peer Marketplace

Buff doesn’t hold your items—it connects buyers and sellers directly via Steam. Sellers list items, buyers buy, and trades happen straight between inventories. This means you can list on multiple platforms simultaneously—but it also makes trade completion dependent on the seller’s approval. .

3.2. Price and Inventory Benefits

• Buff hosts 4.8 million offers, with total item value nearing $195 million. Many skins move faster here than on other platforms .
• Its 2.5% seller fee is far lower than Steam’s ~15%, making it very appealing for sellers.

Features That Make You Go “Wow”

I really love how Buff offers:

• A massive, diverse skin catalog you can explore.
• Competitive pricing and helpful data to set or judge prices.
• A legit ownership (NetEase) and proven track record.
• Low fees—especially attractive if you’re into trading or reselling

Safety and Security: Is Buff Safe?

5.1. Security Basics

Buff uses SSL encryption and is well-known enough that phishing is less likely—though you must still be careful to use the real site (buff.163.com)

5.2. Steam Integration: Handle with Care

You’ll need to link your Steam ID, API key, and trade URL—which is standard for P2P marketplaces, but it does come with risk. If Buff were ever compromised, your API key could be exposed.

• Always use Steam Guard and strong passwords.
• Never share your API key on untrusted platforms.
• Double-check the site URL before entering credentials.

5.3. User Warnings

One Reddit user advised

“Only if you are Chinese WITH a Chinese bank account can you use it. Also make sure it’s a real site. Use CSFloat if you are not Chinese.”
That’s a friendly heads-up—we know what’s legit, but if you’re not Chinese, access can be a hurdle.

Real User Voices: A Human Touch

Some folks share their real experiences:

• Trustpilot:
  • “Great platform, but maybe not for foreigners … it’s safe, it’s NetEase.
  • “I used to love Buff163… a few months ago they made it impossible to sell items without having a Chinese bank account… useless for anyone outside China.
• Reddit: “Only if you are Chinese WITH a Chinese bank account can you use it.

These highlight valuable strengths vs. accessibility barriers.

Why Buff Stands Out—and When It Doesn’t

8.1. What Makes It Stand Out

• It sets the price standard in CS2 trading circles.
• Offers high liquidity, especially for rare or high-tier skins.
• Ultra low fees make it a favorite among active traders.

8.2. Where It Falls Short

• It’s basically a China-first system now.
• Non-Chinese users may find it frustrating or nearly inaccessible.
• Support, interface, and verification all tilt toward Chinese users.

Buff Legit and Safe – Pros and Cons

Pros

• Legit company – Backed by NetEase, a well-known and trusted tech giant in China.
• Low seller fees – Only about 2.5%, cheaper than many marketplaces.
• Huge selection – Millions of skins for CS2, Dota 2, Rust, and more.
• Accurate pricing – Great for checking real skin values.

Cons

Final Thoughts: Is Buff Legit, Safe, or a Scam?

Buff is absolutely legit. It’s backed by a major company, handles huge trade volume, and has a real presence in the gaming world.

Is it safe? Mostly, yes—especially if you follow best practices (use Steam Guard, link carefully, stay on the official site).

Scam? No. But it’s not always easy. Many users outside China feel locked out or unsupported.

So yes: Buff is legit, generally safe, and totally genuine—but mainly built for Chinese users. If you’re outside that circle, you can still use it, but you’ll need patience—and maybe a workaround.
