I just want to tell you that currently there are already 17,243,687 bitcoins in the circulation meaning that still remain 3,756,313 bitcoins that will be mined since there are only 21 Million bitcoins in this world, and in the future people will hard to own even a single one because the amount of available bitcoin will decrease over the years and this is called as deflation. What I'm trying to point out before you buy the altcoin make sure that you already have some bitcoins it will be good if you have a whole one since probably bitcoin's price will be skyrocket.
