I suggest that you buy Bitcoin as much as you can or depends on you whenever the value of it in the market is cheap and hold it and wait for the Bitcoin's price to reaches the highest possible value then sell it. The value keeps on increasing time by time and very unpredictable so investing in here is a better decision. I think investment in the Bitcoin will be a worth value in the future. You see that Bitcoin is becoming a popular and potential currency around the world so it might be a great asset in the long run.
