Poloniex has partnered with payment-processor Simplex, so customers from 60+ countries can use their debit or credit cards to buy bitcoin on Poloniex. Simplex charges a 3.5% fee (or $10, whichever is greater), and customers can purchase as little as $50 worth of bitcoin.
Customers who connect their bank accounts and deposit funds will get their fiat money automatically tokenized to USD Coin (USDC), meaning they’ll get all the benefits of the US Dollar at the speed of crypto and be able to move value at a moment’s notice.
