Poloniex
We are a US-based digital asset exchange offering maximum security and advanced trading features. Trade securely on the world's most active digital asset exchange.
The vast majority of customer deposits are stored offline in air-gapped cold storage. We only keep enough online to facilitate active trading, which greatly minimizes risk and exposure.
Our auditing programs monitor exchange activity 24/7/365. Their job is to report and block any suspicious activity before it becomes a problem.
Any funds you put into the exchange are only used to facilitate trading through your account. Unlike banks, we do not operate on fractional reserves.
