In my opinion, this year is the best year for investing in the cryptocurrency because all of the coins prices are down too deep and this help us to buy more and more coins. But for people that already buy the coin in the 2017 and they are not selling when it's high, they need to wait for a while, but they can also buy more coins. I am sure that in the next year, we will see the rise of cryptocurrency and when it happens, all of the coins prices will reach the highest price.
