SIGEN.PRO Crypto Exchange Review: Is It Still Operational in 2025?

When you hear about a cryptocurrency exchange that charges zero trading fees, it sounds too good to be true. That’s exactly what SIGEN.PRO promised since its launch in 2017. No commissions on trades. No fees on withdrawals. No KYC. Just a simple interface and a mining-based revenue model. But here’s the catch: as of 2025, there’s growing evidence that SIGEN.PRO may no longer be operating at all.

What SIGEN.PRO Actually Offered

SIGEN.PRO wasn’t just another crypto exchange. It tried to carve out a unique space by combining four services into one: a trading platform, a peer-to-peer (P2P) marketplace, a crypto wallet, and a non-registered exchanger. Its name came from Greek symbolism - Sigma (Σ) for knowledge and Energy for vitality. It targeted users who wanted anonymity and low friction, especially in Russian-speaking countries where the interface defaulted to Russian.

Unlike Binance or Coinbase, SIGEN.PRO didn’t handle fiat currency directly. You couldn’t deposit dollars or euros. But you could use its P2P system to trade crypto for cash, bank transfers, or e-wallets like WebMoney or Qiwi. That meant no KYC - a big draw for privacy-focused traders. Your funds were always in the platform’s custody, just like on centralized exchanges. That also meant you didn’t control your private keys. If SIGEN.PRO went down, so did your assets.

The Commission-Free Model That Couldn’t Last

Most exchanges make money from trading fees, withdrawal fees, and spread margins. SIGEN.PRO claimed to charge nothing. Not even for Bitcoin withdrawals, where platforms like Binance typically charge $20-$30. How did they stay alive?

Their answer: mining. SIGEN.PRO operated its own mining operations and used the profits to cover platform costs. This was unusual. Most exchanges don’t mine - they trade. This created a potential conflict: if the platform profited more from mining than trading, did they have an incentive to limit trading volume? Users didn’t report this directly, but the model was never tested under heavy market stress.

The platform supported eight cryptocurrencies: Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), Binance Coin (BNB), Umi (UMI), Ton Crystal (TON), Minter Network (BIP), and Wrapped Bitcoin (WBTC). That’s far fewer than competitors. Binance supports over 1,000. Even Kraken has 200+. SIGEN.PRO focused on a small group of coins with staking potential, which made sense for its niche but limited its usefulness for active traders.

Security: Cold Storage, But No Transparency

WalletScrutiny verified that SIGEN.PRO used a cold-hot wallet system. Most coins were kept offline in cold storage. Only a small portion was in hot wallets for withdrawals. That’s standard practice and a good sign.

But here’s the problem: SIGEN.PRO never published proof of reserves. No third-party audits. No public wallet addresses to verify holdings. WalletScrutiny labeled it “custodial and not verifiable.” That’s not a red flag by itself - most centralized exchanges aren’t transparent - but combined with other issues, it raised concerns.

The platform didn’t require KYC, which helped privacy but hurt trust. Regulators around the world are cracking down on exchanges that skip identity checks. SIGEN.PRO’s refusal to comply meant it could never expand into major markets like the U.S., EU, or UK. That capped its growth early.

Mobile Apps and User Experience

Users consistently praised the interface. CoinIdol and HappyCoin reviews mentioned a “simple and intuitive” design. The mobile apps on iOS and Android were well-rated, with smooth trading and fast order execution. For beginners, it was easy to buy crypto, stake coins, or use the P2P exchanger without registration.

The P2P exchanger was especially handy. You could swap BTC for UMI without logging in. Just pick a pair, enter the amount, send crypto to the provided address, and wait. No account needed. That’s rare in the crypto space.

But the same simplicity became a limitation. There were no advanced order types - no limit orders, stop-losses, or margin trading. No charting tools beyond basic candlesticks. No API for bots. It was built for casual users, not traders.

Why Users Loved It - And Why They Left

The top reasons users stuck with SIGEN.PRO:

• Zero trading and withdrawal fees
• No KYC - fast onboarding
• Simple, clean interface
• Staking rewards on select coins
• Reliable mobile apps

The main complaints?

• Too few trading pairs - only 8 coins
• No fiat on-ramps
• No support for US users
• Lack of transparency around reserves

Most users didn’t complain about security breaches or stolen funds. The complaints were about limitations, not fraud. That’s important.

The Big Problem: Is SIGEN.PRO Still Alive?

This is where things get messy.

In 2020 and 2021, reviews from Cryptowisser, Aptantech, and CoinIdol were positive. The platform was active. Trading pairs were listed. Apps worked. Users were happy.

But today, CoinCodex - a major crypto data aggregator - lists SIGEN.PRO as “no longer operational.” Their warning is clear: “We currently don’t have the necessary data to display this exchange's trading pairs and trading volume.”

ScamAdviser still gives it a 63/100 trust score, calling it “probably legit.” But that score hasn’t been updated since 2023. No new reviews. No blog posts. No social media activity. No official announcement of shutdown.

The domain sigen.pro still loads. The website looks the same. But if you try to trade, you’ll find that order books are empty. Withdrawals may not process. Customer support doesn’t respond.

This isn’t unusual in crypto. Many small exchanges fade quietly. Without funding, regulation, or user growth, they just stop updating. SIGEN.PRO’s mining-based model likely struggled as crypto prices dipped and mining became less profitable. Without trading fees to fall back on, they had no backup revenue.

Who Was SIGEN.PRO For?

SIGEN.PRO was never meant to compete with Binance or Coinbase. It was built for a specific group:

• Users in Russia, Ukraine, or Kazakhstan who wanted to avoid KYC
• Traders who hated paying withdrawal fees
• People who only traded a few major coins like BTC and ETH
• Those who valued simplicity over features

If you fit that profile and used it before 2022, you might have had a good experience. But if you’re looking for a reliable exchange in 2025, SIGEN.PRO is not it.

Alternatives to Consider

If you liked SIGEN.PRO for its zero fees and no-KYC P2P, here are better options today:

• Bybit - offers zero-fee spot trading on select pairs, supports P2P, and has strong liquidity.
• Kraken - low fees, KYC required, but trusted and regulated in many countries.
• LocalBitcoins - best for P2P fiat trades with cash or bank transfers.
• OKX - supports staking, low fees, and over 300 trading pairs.

None of these are perfect. But they’re active. They update. They respond to users.

Final Verdict: Don’t Use SIGEN.PRO in 2025

SIGEN.PRO had a clever idea: remove fees and rely on mining. It worked for a few years. But crypto exchanges need more than a good idea - they need funding, compliance, and scalability. SIGEN.PRO had none of that.

The lack of recent data, the silence from its team, and the official “no longer operational” tag from CoinCodex all point to one conclusion: the platform is dead.

If you still have funds on SIGEN.PRO, try contacting support. But don’t expect a response. If you’re new to crypto, skip it entirely. Choose a platform with transparency, active support, and a clear business model.

The crypto world moves fast. Platforms that don’t evolve disappear. SIGEN.PRO was a quiet ghost - once useful, now forgotten.
