We can't deny the fact that many people become rich because of trading cryptocurrency. They wouldn't become successful in trading if they didn't do some research before. Aside from this forum, can you share to us where can we find a good information that can help us be successful in trading?
There are different kind of traders like day traders, swing traders or those that are long term traders and the strategy would depend on what kind of trader are you. If you trade a coin for short term then look for a related news or event about the coin. One site that I know that post upcoming events for a certain coin is
http://coinmarketcal.com/. Studying why a coin behaves that way would be a big help in speculating what would be the price of the coin in the next hours or days. If you are just starting to learn trading and wants to know the fundamental and technical analysis then
https://www.babypips.com/ would be the site for you. You may know the theories about trading but the best teacher would be experience because you will truly learn what the books are talking about when you do it yourself. If you want to learn in the least amount of time then better have a mentor.
