One of the odd things about occidental folks generally is they tend to spend a bunch of time contemplating the future and thus not living in the present. One description of oriental (Chinese I think) thought is how a river looks when only looking down stream or how the voyage of a ship appears when merely looking at the wake from the stern.
Fact is BTCs are a currency now or, at least fit the definition of "currency" better than FRN (so called "USD").
I have lured a friend who sells batteries/electronics online to get into BTCs and he will soon be offering his wares in exchange for BTC.
The future is already here.
How did you know the future is here unless you contemplated the relationship of the future to the present? Using a similar river analogy, you don't always have to 'be' the river, looking at the bank of the river as you flow past it. You can take the perspective of the river bank which simultaneously holds the potential for past, present, and future river configurations. When we learn past present and future are connected, 'living in the present' isn't as concrete of an idea as you may think.
I only mentioned one perspective of Oriental consciousness. For myself there is no future or past just the eternal now. For now BTCs are here n'est pas?
