The Prime Markets website doesn't load very fast, and I have my doubts about some of the data it presents. All my friends said they had never heard of this company, so I don't want to invest here.

I would not suggest this company. The "expert" advisor is continually pressuring you to increase your investment. Despite my reluctance, I conducted a test withdrawal, which proved to be a significant struggle. The software provides no assistance notes or lessons, resulting in multiple simple errors that my adviser revealed to me after the event. Our conversations were contentious rather than supportive. I didn't feel in command of my account, which included my personal money. A request to close the account was ignored. I got my money back from them. The firm is a terrible sham, and the FCA has blacklisted it, which I did not do. They were a complete waste of time and money
