If he has decided to see not rising by the end of the year as a big disappointment, which is because that is the line he has decided to choose. Disappointment only comes to those who expect too much from the future they cannot predict, rather than trying to take advantage on the moment now, believing surely that the future is good irrespective of when it comes good, and then be able to make substantial decisions by utilizing the opportunity that the market brings now. There is so much in the future that is expected, so, trying to panic unnecessarily or getting disappointed if the market does not move as please, sounds absurd to me.
Many hodlers would strongly disagree with you on this one. They blindly believe that bitcoin will be a huge success in the coming years and thus they keep on holding their bitcoins. Do they expect too much from the future and can they not predict it? It seems to me that they are waiting for the next bull run which should start after bitcoin bottoms out. It may have already but somehow I don't think that their hopes will come to fruition. Bitcoin is most likely going to continue trading in the narrow range of 6-8k, but I don't see the market being overflowing with opportunities. You can't do much in this kind of trading environment.
