Learn to understand market trends. The ability to read a chart is the main skill of a trader, because in one day growth can be replaced by a fall more than once. Adaptation to the situation is very important.
Emotions, especially negative ones, have never helped anyone. Especially when it comes to trading, where you need to be able to build strategies and see the "subtleties" of the market. Both panic and euphoria are dangerous. Control yourself and look at the situation sensibly.
Minimize your risks. Never invest your funds in one cryptocurrency or direction, even if they are very promising now. We recommend distributing funds so that a part is in trading, a part in a hold, a part in mining, a part in ICO and startups.
Before investing, you should have at least a minimal understanding of the strategy with which you will predict all your subsequent actions and, in particular, the way out of position (cryptocurrency). Never play the “lucky lottery” - it will not lead you to anything good!
Following these rules you will be much less likely to face problems and loss of funds.
