If you're from outside of the U.S., you will not have an access to the Robinhood marketplace. Suffice to say, being a regulated business with almost no fees does have its perks. Instead of spamming you here with text, I can give you a guide about the platform and then you can see it for yourself:

Not a bad platform IMHO due to fees and the point that your assets are secure from hacks and market manipulation, though it requires full verification form your side (who doesn't these days).
