Why Poloniex is graded C
Five binary safety criteria — each one passed or not. The more passed, the safer.
- ✗
Regulation
No licence from a financial regulator to hold client funds. Poloniex's user agreement (revised 1 April 2026) is governed by the laws of Panama and shuts out the US, the UK, every EU country and Singapore. Regulators have acted against it more than once — in August 2021 Poloniex LLC settled SEC charges of running an unregistered securities exchange ($10.4 million), in 2021 the Ontario Securities Commission brought allegations against Polo Digital Assets, Ltd. for operating without registration, and in May 2023 Poloniex LLC paid $7.59 million to settle US sanctions violations.

Proof-of-Reserves
Poloniex publishes a monthly Merkle-tree proof of reserves with a per-coin breakdown and a tool to verify your own balance. The 1 October 2026 snapshot shows a total reserve ratio of 100.48% (BTC 100.10%, ETH 100.59%, USDT 100.32%). The report is self-published; no auditor is named. Source →

Insurance Fund
No protection fund covering hacks or losses of client funds is described on Poloniex's own pages. A $100 million "User Protection Fund" was reported in April 2026, but neither its wallet nor the conditions under which it pays out have been published, so we do not count it. Source →

Track record (2+ years incident-free)
Operating since 2014. On 10 November 2023 hackers drained Poloniex's hot wallets; PeckShield estimated the loss at around $125 million, and Poloniex said it would fully reimburse users. An earlier breach in March 2014 took 12.3% of its bitcoin. Since November 2023 — almost three years — we found no hack, withdrawal freeze or loss of client funds, so it passes our two-year rule. The regulators' settlements are counted under regulation. Source 1 → Source 2 → Source 3 →

Your money, this pair
How much will you earn?
Method: monthly compounding (1 + APR/12)ⁿ, where APR is the exchange's stated rate. The realized 12-month return is slightly higher due to reinvestment. Rates may change. Not financial advice.

How JST earns on Poloniex
When you deposit JST into Poloniex's earn product you receive 0.5 % APY as a Flexible rate. The platform puts the asset to work and shares the yield — your balance grows without you doing anything.
This is a base rate, not a promotional teaser: it's what an ordinary deposit actually earns. Poloniex carries a YieldScope safety grade of C, so weigh the yield against platform risk — a higher rate on a weaker grade is not automatically a better deal.
Rates on JST move with lending demand and market conditions. We re-check them daily and keep a history, so you can see whether today's number is unusually high, unusually low, or steady.
