to become a professional investor must have a lot of knowledge or experience in business or trading, when someone takes action that will be done for the future, he will definitely think first before doing it and he will look for more information about the project he will follow so as not to fall into the wrong project. recently I posted about crypto on my social media account and many people asked me how to play crypto then they asked me to teach them how. can we teach them without having to meet? I think it's difficult! maybe friends here can share ways to solve the problems above.
