PrimeXBT, a Bitcoin-based margin trading platform offering up to 500x leverage across forex, stock indices, commodities, and cryptocurrencies, has announced the debut of a new, progressive fee system, rewarding the platform's most active traders with up to a 50% discount on all trading fees. PrimeXBT continues to bolster its competitive advantage by reducing the already low fees offered on its advanced trading platform, encouraging increased trading activity and allowing traders to retain even more of the profit generated from successful positions.
