Are there any other platforms worth looking into?
If you want to dip your toes a bit first and not nose-dive in immediately, I suggest trying out platforms that has a virtual portfolio feature. eToro[1] has this feature; pretty much they give you $100,000 of play money, and you can trade with all your heart's content without actually risking your money. You can also trade assets outside of crypto aswell.
Best of luck!
