As I was in a same situation like you a few months back I can tell that you will have to make up your own strategies once you learn the basics of trading. Youtube and this forum are a good source to learn some basic concepts like placing limit orders, Other types of orders to minimize loses. Off the hook, try demo trading as many exchanges have this feature. Make a list of promising coins and keep an eye on them.

Start with a small amount. Buy Low- Sell High- Rinse Repeat.

As you progress you will learn how to make quick decisions. You also need to be mentally strong to avoid yourself from panic selling. Make sure not to buy at an all time high price. You will need to resist this urge or FOMO as it is called in Crypto Lingo.

Good Luck and Happy trading!
