Overall, I like this service, although it has its drawbacks. Trading "anonymously" is not possible: trading is accessible, but to withdraw funds, you will need to verify your identity; otherwise, the operation may be blocked. For verification, you need to provide scans of documents confirming your identity and place of residence. It's unclear what happens to these documents after submission: are they stored, deleted, or at risk of a leak? You have to accept this practice, especially since it's typical for most platforms. I also had a transaction frozen once without explanation. This happened when I didn't complete the second stage of verification, and the operation seemed suspicious to them, so they marked it as "pending confirmation." This occurred during a withdrawal, and I couldn't access my money from the exchange for about two weeks. In the end, it seems I was "verified," and the withdrawal worked. Additionally, there is no Russian version or affiliate program. This is not critical; you can work without it, but it would be much more convenient with localization. Other than that, I have no complaints: the exchange has a good turnover and attractive trading conditions, and the fees are reasonable, so working here is comfortable. I don't use exchanges, including Poloniex, as a wallet for storing cryptocurrencies and don't trade solely on it—diversification is important in the crypto market. The reason is simple: I'm afraid the service could turn into a scam, even though Poloniex is a giant in the market, but no one is immune to that.
