You should calm down first. Then start searching about the trading methods. Day trade, mid trade and long term trade are main 3 categories.
Never pay attention to those pump and dump groups. They're all fake.
Don't get fooled by others. They man try to manipulate you by giving you wrong information.
Always make decision based on your understanding, try to watch the market before buying, avoid putting all in one coin and always be updated in all your holdings. It is hard at first but as time passed by it will be easy for you then.
Yeah don't follow tips like which coins will pump and dump because many of them may give false news, yeah agree to make choices
according to what you understand and what you have calculated before, understand the market well, as time passes you will the more expert dude..
