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.
This is a awesome tricks for newbies I definitely welcomed the fact you are putting up some knowledge in them, and in my own add up I will also say to newbies never start a trade if you know you ain't capable to understand the market and also don't start a trade with low capital.
