I am sorry to have to say this mate, but you cant do anything with 4 dollars, better if you buy a coca cola with that amount.
And i dont suggest you to trade with that amount as the member above said, it will take you months to double that amount by trading, and it is not worthly to spend one or two months only to make a profit of $4... try to get a job and invest that money, trade with it and then you will have a good money.
good luck
Lol coca cola.
The thing is the money was hard to come by and I don't want to waste it. I want to put it into production to yield more instead of praying for bitcoin to go high in price.
