Is Plus500 legit?

Considering Plus500 for CFD trading but seeing mixed reviews online.

They're FCA regulated and publicly traded on London Stock Exchange, which seems legitimate. But Trustpilot shows a lot of withdrawal complaints.

Has anyone here actually used Plus500 long-term?

Specifically interested in:

- Withdrawal process (how long, any issues?)

- Spread quality during volatile markets

- Platform stability

- Customer support responsiveness

I know they're popular in Europe but want real user experiences before opening an account.

Any feedback appreciated.
