First up, the trading costs caught me off guard. They don't make it clear upfront how much you'll end up paying, and it adds up fast. Then there's the issue with spreads. They're really wide. This means every trade starts off losing more money than it should. It's tough to make a profit when you're always starting from behind. And don't get me started on their trading platforms. They're just terrible. It's hard to use, crashes a lot, and sometimes it's so slow that you miss out on good trading opportunities. It feels like they haven't updated their system in years.
