i think people who put all their trust in bitcoin are kind of shortsighted to the extent that what you just mentioned. it would be really arrogant and conceited to think that something better is not going to come along and bitcoin will die a slow death. it's just the way things are. no wonder some of those old satoshi era wallets woke up recently and starting hitting the sell button they know what's up. 

use it for what it is good for but don't expect it to make you a millionaire or billionaire without you doing any work. it might not even be a good store of value. in the long term. but i know people don't want to hear that...
