Poloniex Savings Calculator
How Poloniex Savings Works
Poloniex offers a savings program where you can earn interest on BTC, ETH, and USDT. Rates vary based on market conditions, but they've reached up to 8-10% APY on stablecoins in the past. Your funds are locked for 7-30 days depending on the coin.

Important: Poloniex requires a 7-30 day lock-up period for savings. Interest rates vary based on market conditions and coin type. This calculator uses 8% APY as a default rate for illustration purposes.
Poloniex isn't what it used to be - and that changes everything
If you're looking for a crypto exchange to trade Bitcoin, Ethereum, or altcoins, you might have heard of Poloniex. It was once one of the biggest names in the space, especially back in 2017 when Bitcoin hit $20,000. But today, things are very different. Poloniex shut down its operations for U.S. users in October 2023. If you live in the United States, you can no longer sign up, deposit, or trade on the platform. Even if you had an account before, you had to move your funds out by the deadline. This isn’t a minor update - it’s a full exit from one of the world’s largest crypto markets.
What Poloniex still offers (if you’re outside the U.S.)
For users outside the U.S., Poloniex still runs. It supports around 100+ cryptocurrencies, including major ones like BTC, ETH, XRP, and LTC. It doesn’t offer direct bank deposits or fiat on-ramps. That means you can’t buy crypto with USD, EUR, or NZD directly on Poloniex. You need to buy crypto elsewhere - say, on Coinbase or Kraken - and then transfer it over. This adds a step for beginners, but it’s not unusual for institutional-focused platforms.
What Poloniex does well is crypto-to-crypto trading. It has deep liquidity on major pairs like BTC/ETH and ETH/USDT. The platform’s API is built for high-frequency trading. It has low latency and high rate limits, which is why hedge funds and algorithmic traders still use it. If you’re running bots or making dozens of trades a minute, Poloniex’s infrastructure can handle it better than many newer exchanges.
Security: Trusted, but with scars
Poloniex has a reputation for being one of the more secure exchanges - and for good reason. All withdrawals and API access require two-factor authentication (2FA). It doesn’t allow withdrawals without SMS or Google Authenticator verification. One verified G2 user called it “one of the safest and most reliable crypto exchanges founded in the USA.”
But here’s the catch: Poloniex has had security breaches in the past. In 2014, shortly after launch, it lost over 12% of its Bitcoin holdings in a hack. That’s a long time ago, and the platform has since hardened its systems. Still, that history lingers in reviews. Users who’ve been around since 2015 remember it. Newer traders don’t. So if security is your top priority, you’ll want to weigh that past against current practices.
The big downside: No fiat, no U.S. users, and limited coins
Poloniex’s biggest limitations aren’t technical - they’re strategic. First, no fiat. That’s a dealbreaker for most retail traders. If you don’t already own crypto, you can’t start here. You need to buy it on another exchange, then send it over. That’s two sets of fees, two sets of wallet addresses, and two chances to make a mistake.
Second, the coin selection is narrow. While exchanges like Binance or Crypto.com list over 250 coins, Poloniex sticks to about 100. That’s not because it’s outdated - it’s by design. The team says they focus on quality over quantity. They avoid low-liquidity, speculative tokens that often turn out to be scams. One trader on G2 said: “I actually like that they don’t list every new meme coin. It keeps me from getting scammed.”
But that same trader also admitted: “I wish they added more DeFi tokens and newer projects.” If you’re into niche DeFi coins, NFT-related tokens, or Layer 2 solutions like Arbitrum or Polygon, Poloniex might feel too conservative.
Passive earnings? Yes - but only if you’re patient
One feature Poloniex still offers that many exchanges don’t is a savings program. You can lock up your BTC, ETH, or USDT and earn interest. Rates vary by coin and market conditions, but they’ve been as high as 8-10% APY on stablecoins in the past. That’s competitive with what you’d get on Celsius or BlockFi - before those platforms collapsed.
The catch? You can’t withdraw instantly. Most savings options require a 7-30 day lock-up. If you need access to your funds quickly, this isn’t for you. But if you’re holding long-term and want to earn yield without trading, it’s a solid option.
Customer support: A weak spot
Don’t expect fast replies. Multiple reviews on G2 and Cryptoninjas.net mention poor customer support. Emails often go unanswered for days. Live chat is either offline or automated. If you run into a problem - say, a delayed deposit or a failed withdrawal - you’re on your own for a while. This isn’t a dealbreaker if you’re an experienced trader who knows how to handle transfers and security. But if you’re new to crypto and need help, Poloniex will frustrate you.
Who is Poloniex really for?
Poloniex isn’t for everyone. It’s not for beginners. It’s not for U.S. residents. It’s not for people who want to buy crypto with their credit card.
It is for:
- Non-U.S. traders who already own crypto and want deep liquidity on major pairs
- Institutional users running automated trading bots
- Long-term holders who want to earn passive interest without active trading
- Traders who value security over flashy features
If you fit that profile, Poloniex still works. But if you’re looking for a simple, all-in-one exchange to buy, trade, and sell crypto with fiat - keep looking.
What happened to Poloniex? Why did it leave the U.S.?
Poloniex didn’t just decide to quit the U.S. market because it wanted to. Regulatory pressure forced its hand. The SEC has been cracking down on exchanges that don’t comply with U.S. securities laws. Many platforms - including Binance and Coinbase - spent millions to get licensed. Poloniex chose a different path: exit cleanly.
That decision saved them legal costs, but it also cut off 40% of their potential user base overnight. The move signals that Poloniex is no longer trying to be a global retail giant. It’s narrowing its focus to professional, international traders who don’t need fiat support.
Alternatives if you’re outside the U.S.
If you’re outside the U.S. and want more coins or fiat options, consider:
- Binance - More coins, fiat on-ramps, lower fees, but stricter KYC
- Kraken - Strong security, good support, supports USD/EUR, but slower UI
- Bybit - Great for derivatives, high liquidity, no U.S. users, easy API
Poloniex still holds its own in API performance and institutional trust. But if you want simplicity, more coins, or fiat access, you’ll find better options.
Final verdict: Still relevant? Only for a niche
Poloniex isn’t dead. But it’s no longer a mainstream choice. It’s a specialized tool - like a high-end racing car. It’s fast, reliable, and built for experts. But if you’re not already on the track, you’ll struggle to get in.
For non-U.S. traders with crypto already in hand, who care about security and API performance - Poloniex still delivers. For everyone else? There are better, simpler, and more accessible exchanges today.
And if you’re in the U.S.? It’s too late. Move your assets. Find another platform. Poloniex won’t be coming back.
Is Poloniex still operational?
Yes, Poloniex is still operational - but only for users outside the United States. As of October 15, 2023, the exchange shut down all services for U.S. residents. If you’re in the U.S., you can no longer access your account or make trades. International users can still log in, trade crypto-to-crypto, and use the savings feature.
Can I deposit USD or EUR on Poloniex?
No, Poloniex does not support fiat deposits. You cannot deposit U.S. dollars, euros, or any other government-backed currency. You must first buy cryptocurrency on another exchange - like Coinbase, Kraken, or Binance - and then transfer it to your Poloniex wallet. This adds complexity, especially for beginners.
How many cryptocurrencies does Poloniex support?
Poloniex supports around 100+ cryptocurrencies, including Bitcoin, Ethereum, Cardano, Solana, and major stablecoins. This is fewer than competitors like Binance or Crypto.com, which offer over 250. Poloniex intentionally limits its listings to avoid low-quality or scam tokens, focusing on established projects with strong liquidity.
Is Poloniex safe to use?
Poloniex has strong security features, including mandatory 2FA for withdrawals and API access. Many professional traders consider it reliable. However, it has a history of security breaches - most notably in 2014, when it lost over $12 million in Bitcoin. Since then, it has improved its systems significantly. Still, if you’re storing large amounts long-term, consider moving funds to a hardware wallet.
Does Poloniex offer interest on crypto holdings?
Yes, Poloniex offers a savings program where you can earn interest on BTC, ETH, USDT, and other supported coins. Rates vary, but they’ve reached up to 10% APY on stablecoins in the past. However, your funds are locked for 7 to 30 days, depending on the coin. You can’t withdraw instantly, so this is best for long-term holders, not active traders.
Why did Poloniex shut down U.S. operations?
Poloniex exited the U.S. market in October 2023 due to increasing regulatory pressure from the SEC. Unlike exchanges that spent millions to comply with U.S. laws (like Coinbase), Poloniex chose to shut down its U.S. services entirely. This allowed them to avoid legal costs and fines, but it also removed access for millions of potential users. The move reflects a broader trend of crypto platforms retreating from strict regulatory environments.
Is Poloniex good for beginners?
No, Poloniex is not ideal for beginners. It lacks fiat on-ramps, has a complex interface designed for traders, and offers poor customer support. If you’re new to crypto and want to buy Bitcoin with a credit card or bank transfer, use Coinbase, Kraken, or Binance instead. Poloniex is built for experienced users who already own crypto and need fast, secure trading with institutional-grade APIs.
What are the best alternatives to Poloniex?
If you’re outside the U.S. and want more coins or fiat access, try Binance (best overall), Kraken (best for security and support), or Bybit (best for derivatives). If you’re in the U.S., Coinbase and Kraken are your best options for compliance and ease of use. Poloniex’s strengths - API performance and security - are matched by these platforms, with better user experience and broader features.
