Definitely the hype that surrounds the coin has a lot to do with the initial stages of a coins entry into the market, just be careful if you do heavily invest in a coin that you are not the one left holding a huge bag, and don't be greedy

a few times I have got just a little bit too greedy after a coin has been top volume and kept on growing and then I took my eyes off it for a couple of days and I ended up making minimal instead of maximum profit.
