Before investing into Bitcoin, you must first research about it. Gain a LOT of knowledge about it so that you know how to move you money. For now, my advice for you is not to put all eggs in one nest. In other words, put your hard-earned money into different investments so that if one falls down, you have other investments to support you.
A wise strategy for a bitcoin is: You should know and observe the flow of transaction of your bitcoin, good timing when you buy and sell your tokens, patience for you to study the flow of every move of your tokens and lastly I believe don't get your emotion involve in any decision or transaction that you've maid because in my personal experience I feel down, sad and depress when the time I sell my tokens and the next day it pump up or increase the value of my token. And then I wait to decrease the token and Ive buy some tokens again.
