Is Poloniex safe to use?

  • Regulation. Poloniex has an AML/KYC policy, and is registered in the Seychelles. It does not serve customers in jurisdictions where it’s not appropriately licensed or regulated to offer cryptocurrency trading services. It was formerly owned by prominent Goldman Sachs-backed tech company Circle, before spinning out into a separate company. It still maintains close ties with Circle.
  • Verification process. Poloniex traders are required to provide their full name, and Poloniex may ask for additional identification such as a driver’s licence or passport. In certain circumstances it may require users to submit additional information for enhanced due diligence.
  • Security features. Poloniex has insurance coverage for the crypto assets on its platform, it stores a large portion of customer funds offline and follows industry best security practices.
  • FCA status. Whilst crypto trading isn’t regulated in the UK, the Financial Conduct Authority (FCA) maintains a register of crypto firms that have passed its AML and counter-terrorism checks. However, Poloniex has no UK entity and therefore you won’t find it on the FCA’s register.

Poloniex was founded in 2014, and experienced its first and only hack a couple of months later, when a large amount of Bitcoin was stolen through an obscure bug in Poloniex’s trading software. Losses were socialised among all its users, who were then paid back over time.

The next major issue was in 2019, when an obscure and illiquid cryptocurrency called CLAM, which could be margin traded on Poloniex, experienced a flash crash. The issue was two-fold: firstly the illiquid CLAM markets meant liquidations could not process as normal. Secondly, margin borrowers were using CLAM as collateral for their loans. The result was that margin borrowers could not repay their loans, resulting in a total loss equivalent to 1,800 BTC for Poloniex margin lenders, as the BTC loans were all held in a common pool.

Following the incident, Poloniex committed to reimbursing affected customers through fee rebates, and preventing it from happening again by stopping margin trading on obscure and illiquid cryptocurrencies.

What else do I need to know about Poloniex?

Poloniex was founded in the USA in 2014, and for a time it was the world’s largest and highest-volume Bitcoin exchange.

But it had difficulty scaling upwards to support growing cryptocurrency demand, and following the Bitcoin boom of late 2017 it was acquired by Circle, which reoriented Poloniex towards becoming a professional and well-regulated cryptocurrency exchange.

The regulatory climate of the USA precluded this though, and in late 2019 Poloniex spun off from Circle as its own company, and barred US customers to focus more strongly on the international markets.

In a nutshell


  • Wide selection. Poloniex offers a wide selection of cryptocurrencies.
  • Margin trading. Margin trading is available across a range of pairs.
  • Trading APIs. Poloniex trading APIs make it a suitable platform for bot trading and other advanced strategies.
  • Margin lending. Poloniex’s peer to peer margin lending market offers more ways to earn from cryptocurrency.


  • Middling fees without volume discounts. Unless you can access the volume-based fee discounts, Poloniex’s trading fees are not the most competitive.
  • Varying liquidity. Poloniex’s liquidity varies across its markets, and runs low in some places.
  • No direct fiat trading. Poloniex no longer offers direct fiat to cryptocurrency trading.
