Whatever the reason was, our belief should never fade. Just HOLD and BUY MORE! Bitcoin and all other legit altcoins are here to stay. Believe that! 
Yes!! Im with you. If you ever read my posts, youll see that I talk a lot about believing,too. I see believing in something attributing value to that something. For that reason belief= power and as you said above, if our belief in bitcoin or similar fades radically so will bitcoin, but to stop it doing so we just have to believe in what we have up until now. As someone once said to me who is very wise, There are finite games and infinite games. Theres those who see a quick buck and thats what they are in the game in question for. Then you have infinite games where the players play to keep the game going, not in and out again looking for the fall and end We are playing an infinite game here. I really do believe in bitcoin, that it will never fall even it become low and low.
My first time seeing this kind of business really makes me feel that I have and i need to invest also in bitcoin just what my sister and brother do. Because i really dont think it will disappear in an instant. Now that every country is accepting it, I think it will never be perish.
Normally bitcoin are not stable so you dont have to worry if it gets too low because soon it will rise again.
