I need advice on how to improve my trading because I really want to do this
Yes lost of negative spreading. But do not bother about that. No need any articles to learn about trading. Because this is the right place to learn and improve yourself. Just go to Trading discussion session read other post and gain knowledge. Instead of keeping all the money in single coin, better split into other altcoins. Also you need patience to gain profit. Initially start it with a small amount so that loss will also be less. With this small initial amount you can make only a minimal gain, but can gain much experience and knowledge about the trading. Once you are confident as much with trading they you can go ahead with large amounts.
