New Poloniex fees structure coming May 15
Poloniex are set to roll-out the following changes to their new maker-taker trading fees.
Trading fee tiers will be based on 30-day volume in US Dollars, not Bitcoin. They want you to have reasonable expectations for the fees you will pay based on how much you trade, regardless of drastic movements in currency prices. Going forward, Poloniex will be calculating your rolling 30-day trading volume based on the daily average of the BTC-USD rate.
Poloniex are lowering trading fees across the board. To bring their pricing more in line with the market standard, they are lowering their starting taker fee to 0.20% and their starting maker fee to 0.10%.
Poloniex are lowering volume thresholds for fee discounts. Fees for makers will go to 0% when they trade $7,500,000 in a 30-day period; fees for takers will go to 0.10% when they trade $30,000,000 in a 30-day period
Remember that you can check your current tier by visiting the Trading Tier Status page of your Poloniex account.
