SIGEN.PRO Crypto Exchange Review: Fees, Coins, and Is It Still Operational?

If you're looking for a cryptocurrency exchange with zero trading fees, SIGEN.PRO might have caught your eye. Back in 2020 and 2021, it was praised for being simple, fast, and completely commission-free. But today? Things are far from clear. Some sites say it's still running. Others say it’s dead. And if you're trying to trade right now, you might be walking into a ghost town.

What SIGEN.PRO Actually Offered

SIGEN.PRO wasn't just an exchange. It was a bundle: crypto trading, P2P trading, a built-in wallet, and even a no-signup exchanger. All wrapped in a Russian-language interface with optional English, Spanish, and a few other languages. It targeted users who wanted anonymity and didn't want to deal with KYC.

Unlike Binance or Coinbase, SIGEN.PRO didn't hold your fiat money. You couldn't deposit dollars or euros directly. But you could trade crypto for crypto - and that’s where the no-fee model came in. Every trade, every withdrawal, every swap? Free. No hidden costs. No maker-taker spreads. Just pure, uncut crypto movement.

How did they make money? Not from you. They mined crypto. Their revenue came from running mining operations, not from charging traders. That’s unusual. Most exchanges rely on fees. SIGEN.PRO bet on mining. It worked… until it didn’t.

Crypto Selection: Limited but Focused

SIGEN.PRO never tried to be the biggest exchange. It kept things tight. At its peak, it supported eight coins:

• Bitcoin (BTC)
• Ethereum (ETH)
• Litecoin (LTC)
• Binance Coin (BNB)
• Umi (UMI)
• Ton Crystal (TON)
• Minter Network (BIP)
• Wrapped Bitcoin (WBTC)

Notice anything missing? No Solana. No Cardano. No Polkadot. No Dogecoin. That’s because SIGEN.PRO wasn’t chasing volume. It focused on coins with staking potential - especially UMI and TON, which were promoted as high-growth assets. If you wanted to stake, this was a place to do it. If you wanted to trade the top 50 coins? You’d be disappointed.

That’s the biggest complaint from users: too few pairs. You couldn’t trade ETH for BNB directly. You had to go through BTC. It made trading clunky. And when new coins exploded in 2021 and 2022, SIGEN.PRO stayed frozen in time.

No KYC - But Also No Fiat

One of SIGEN.PRO’s biggest selling points was no identity verification. You didn’t need to upload a passport or selfie. That’s rare for any exchange that’s been around since 2017. But here’s the catch: you couldn’t deposit fiat either. No bank transfers. No credit cards. No PayPal.

So how did you get money in? Through P2P. You found someone else on the platform who wanted to trade crypto for cash, bank transfer, or e-wallet. SIGEN.PRO just connected you. No guarantees. No chargebacks. No protection. If the person disappears after you send crypto? You’re out of luck.

That’s the trade-off: anonymity without safety. For users in countries with strict capital controls or where banking is unreliable, this made sense. For everyone else? It was risky.

Wallets: Custodial and Cold-Storage

SIGEN.PRO held your keys. Always. That makes it custodial - just like Coinbase or Kraken. You didn’t control your private keys. If the platform went down, so did your coins.

But they did use cold storage. Most of the crypto was kept offline. Only small amounts were in hot wallets for withdrawals. That’s a good practice. WalletScrutiny confirmed it in 2023. So technically, the security model was sound.

Still, custodial means one thing: you’re trusting them. And when a platform doesn’t have public audits, transparency reports, or regulatory oversight, that trust becomes a gamble.

Mobile App and Ease of Use

The app was clean. Simple. No clutter. You could buy, sell, stake, and swap with a few taps. App Store and Google Play reviews from 2020-2021 were mostly positive. Users called it intuitive, especially for beginners.

The exchanger feature was even simpler. No account needed. Pick a coin pair. Enter the amount. Send your crypto to their address. Wait. Get the result. Done. That’s the kind of frictionless experience most exchanges still can’t match.

The Big Problem: Is SIGEN.PRO Still Alive?

Here’s where it gets messy.

As of early 2026, CoinCodex - a trusted crypto data aggregator - lists SIGEN.PRO as “no longer operational.” No trading pairs. No volume. No data. Just a red warning flag.

But ScamAdviser still gives it a 63/100 trust score - labeled “probably legit.” That suggests the website is still up. Maybe. But no recent user reviews. No updates from the team. No press. No social media activity since 2022.

Experts like WalletScrutiny say the platform was “not verifiable” - meaning they couldn’t confirm if the cold wallets were real or if the mining operations were even happening. That’s not a good sign.

And here’s the kicker: if SIGEN.PRO shut down, your coins are gone. Forever. No customer support. No recovery process. No legal recourse. They never registered with any financial authority. You’re on your own.

Who Was This For?

SIGEN.PRO was never meant for Americans. It blocked US users from day one. It wasn’t built for regulators. It was built for Russian-speaking crypto users who valued privacy, speed, and zero fees over variety and safety.

It worked for a while. Especially when staking UMI and TON looked like a goldmine. But when those coins didn’t deliver, and when major exchanges started slashing fees too, SIGEN.PRO had no way to adapt.

Its business model - mining to cover costs - was fragile. Mining profits dropped. Fees stayed zero. No new coins added. No marketing. No updates. And then… silence.

Alternatives If SIGEN.PRO Is Dead

If you’re looking for zero-fee trading today, here are real options:

• Bybit - Free spot trading, low withdrawal fees, supports 500+ coins.
• KuCoin - No fees on spot trades for certain pairs, strong staking options.
• OKX - Zero trading fees on select tokens, excellent mobile app.
• LocalBitcoins - If you want P2P without KYC, this is still the leader.

None of these are perfect. But they’re active. They have data. They have users. They have support.

Final Verdict: Don’t Use It

SIGEN.PRO had a great idea: no fees, no KYC, simple interface. For a short time, it delivered.

But now? It’s a ghost. CoinCodex says it’s dead. No one’s updated the site. No one’s responded to complaints. The mobile apps might still download - but they won’t connect. Your money is at risk.

If you still have coins on SIGEN.PRO, try to withdraw them - immediately. If you can’t, you’ve lost them. If you’re thinking of signing up? Don’t. Walk away. The risk isn’t worth it.

There are better, safer, active exchanges out there. You don’t need to gamble on a platform that may have vanished without a trace.
