When exploring crypto brokers on MT5, FXOpen and IC Markets are popular choices due to their wide cryptocurrency selection. Spreads and fees can vary greatly, often starting from 0.1% per trade, so compare them carefully. For security and reliability, consider FTX or Binance, known for their robust platforms, though you need to check their integration with MT5 specifically. Some users report lag in order execution during high volatility, so ensure the broker has a strong reputation for performance. Look for brokers offering advanced charting tools and analytics on MT5 to enhance your trading experience.
