Again, if there's value in the system why all the bitcoin holders must run out of that system to benefit? Literally every bitcoin holder is proof that bitcoin system is worthless.
Because it is the same for every currency. You can never benefit from a currency if you do not trade it, it does not matter if there is some kind of value (like debt) stored in it or not. Or how can you benefit from holding a 5 dollar bill that you are not able to trade for something?
