So, there are supposedly more than 18,000,000 of these valuable coins or tokens in the bitcoin system. A half a trillion dollars worth of assets. And yet, all those people that are holding those assets, are unable to even eat an apple or put a single dollar into a pocket if someone doesn't voluntarily enter the system and give them that apple or a dollar.
That is the same for every currency on the planet. You always have to exchange the currency for something else, that is the whole point of it.
