No one knows what is high and low in bitcoins, and price of bitcoins doesn't boost up in a single day, you need to wait for a long time to make profits from it so I don't think that its a fast way to earn them.
Forgot he asked something fast, my bad
no one knows how to earn fast in bitcoin we need always to wait for a long time to have big income, there is more method to earn with bitcoin but you need to have patience on it.
