I would like to ask the people who joined this community in its first years. What tip you could give new members who just got into crypto
Better to look around and explore this community first, read and take down notes. There will be a lot of information overload, but that's good though, at least you will learn how to filter all this information to your advantage.
Others have mentioned a lot already, but it will be a continuous journey, specially if you chooses to become a full time trader. So it might take years for you to learn but there are no shortcuts, you have to work really hard to reach your goals.
