I'm planning to quit my job for full time soon but for now I'm gathering information about mining hardware and stuff. I'm preparing the ground so to say 
Im thinking of this too but different way to earn, I prefer trading because mining is too technical for me and I dont know what my electric bill will cost me.Planning to quit your job and you will do trading? Look like you don't know the meaning of TRADING. To earn from trading, it involves the "price" and "time". Since you will get your source of income in trading, you have to convert your bitcoin fiat whatever price it is. See the picture here?
Yes I know and to avoid that I need to buy low sell high, atleast you should know that right?
That is the basic rule of trading but the fact is no one knows what is low and what is high as the price of bitcoin cannot be predicted, so buy and sell when you are comfortable with price.
