Unlike online casinos, where they pretend there’s a split between beginner and experienced platforms (but there’s actually no difference), Forex brokers do kinda have this division. Brokers that are better for beginners usually have things like low entry thresholds, cent accounts, demo accounts, and a really easy-to-use interface. Basically all the stuff that helps you learn fast and practice without too much risk.
I kinda think the whole “user-friendly interface” thing is overused. I mean, any platform should have a good interface that just makes it easy to use. But I do agree about the cent accounts, demo accounts, tight spreads and all that. You can read about all of it in this review, I recommend it https://brokersinsider.net/exness/. It’s written in a simple and clear way, so a newbie will totally get it. Also, that site has tons of guides and trading tools that will probably come in handy later.
