That's just the textbook definition of sunk cost fallacy.  If anything you are just proving my point.  We spend a bunch of time, resources, and energy to create a virtual commodity (bitcoin) that has no real value, especially if bitcoin died.  If you spent all that same time, effort, and resources to dig up silver instead, worst case scenario you could convert them to 29% efficiency solar panels in the end.  It's crazy to waste time and resources on a black hole called mining for an imaginary resource when you can mine for a real resource instead.

Claiming that you NEED bitcoin to send money to China is also another fallacy because as I've stated a million times, bitcoin is only a currency and not money or the base of Exter's pyramid.  Just like the Chinese wouldn't want an infinite stream of digital US T-bills, they would also not want a continuous stream of bitcoins.  They are going to want some type of REAL WORLD good or service for their trade so you will be shipping them something in a large ship anyway.  You do not eliminate the movement of real world goods by using bitcoin.

Here we can return to the understanding that money has the practical value of creating games for traders.  These are games with transferable utility, but if the money were not available, the game of the traders would be a game without transferable utility and thus naturally a game with less efficiency with regards ot the possibilities for the participants to maximize their combined gains.~Ideal Money
