2018 has been one of the worst years if not the worst in the crypto industry.
in my opinion not everything what you say is true, there are people who are happy with the decline in the price of bitcoin because it is their time to buy as much as possible, because they know that in 2018 yesterday was the right time to buy and then save it for some time. so I don't agree with you about this.
Worst year for those who are panicking but for those who are still optimistic, for i know they have bought more top coins that time and because of that they earned already right now. Im glad that 2018 gives me opportunity to invest and earn more profit, i will do the same all over again if the market dumps again but its sad to know that we cant see a lower price anymore.
