Here are some tricks if you are new to crypto world.
For me i found it good to use 3 part trading trick.
1. Suppose you have total budget of 900$, first thing is do proper research before you invest. Once your research is done , buy coin of worth 300$....
2. Now look into market, if you think you are in profit then book your profit and wait for dip, but if you are in loss then wait some more time for more dip and pick some more coins.
3. now if you see market dip more and more, then wait and wait for best time and buy for further 300$. By this way you can balance your high purchase with low purchase because at some moment it will pump if you think you invest in good project.
So 3 part trading is best thing.
As you said
research before you invest. This is the major thing and has two different categories in which research needs to be done.
1. Fundamental Analysis.
2. Technical Analysis.
Fundamental Analysis: is about analyzing any assets/companies fundamentals like annual reports, quarterly performance etc given a financial year.
I prefer
https://coinswitch.co/news/ as they keep updating all news and current price prediction.
Technical Analysis: is about reading the price charts (graph) of the asset, understanding the masses behavior and psychology etc (the purpose of technical analysis)
I prefer TradingView for plotting my strategies and there you can also follow good traders so that you can have there prediction for comparison.
