Investing in bitcoin is a clever decision now because very soon it's price and demand will increase as both are directly dependent on each other. So if you but bitcoin and hold got 6 months then also you could get $100 just by doing nothing but hold your $800. I think it's not a bad idea
It depends on the volume of bitcoin that you are going to buy. And no doubt that bitcoin is really a good investment nowadays because if you are that type of person that doesn't have an availability to have an investment because of lacking of funds. Then bitcoin is for you and by just simply holding it effortless, you have a chance to get profit.
Buy bitcoin earlier is better. I think for this month the low price of bitcoin is about $830-890 I am not sure that bitcoin price can be lower than this. Yeah that is my oppinion.
