Is 50x legit?

Excuse me, could you please clarify what you mean by "50x legit"? Are you referring to a cryptocurrency trading platform or exchange that offers 50x leverage? If so, it's important to note that while leverage can amplify your profits, it also magnifies your losses. So, whether or not "50x" is "legit" really depends on a variety of factors, such as the reputation and security of the platform, the fees they charge, and whether they comply with relevant regulations. It's always a good idea to thoroughly research and understand the risks involved before trading with leverage.
