It is no longer an argument the Universe is actually expanding faster and faster. As long as human consciousness does the same so will our progress in the material world. That includes Bitcoin or other virtual means of exchange will become more prolific. It is really a no brainer. A Government that adopts bitcoin as currency, is saving it's self hundreds for millions of dollars in coining and engraving costs. For business, a virtual currency that has no "gate fee's" associated with the vendor receipt of funds. Instead you have the consumer paying for the use of the virtual system at the time of receipt of the Bitcoin. Not to mention that a convenience store that accepts Bitcoin, will not be a target for robbers any longer. How could the businesses of the world over look the obvious value of Bitcoin. Lastly, unlike the dollar Bitcoin is volatile, it has great potential to go up and down making it an investment vehicle. Something the US Dollar would never be good for.
I grant you that Bitcoin does have the ability to make significant drops. However it's history shows a steady and continued pattern upwards. As more countries and businesses accept Bitcoin, the more it's value will grow, in spite of periodic sharp drops
There are a few theories trying to explain the
ultimate destiny of the Universe, and the concept of Big Rip is one of the most popular among cosmologists (and no, I'm not one of them)
I dont think that if the price per 1 BTC will be shooting through the moon and farther we can call it a Big Rip for Bitcoin. Bitcoin will not be torn apart in that case. On the contrary, it will become stronger than ever before and the Bitcoin holders will enjoy that time very much. No one, not even an atom, will enjoy the Big Rip in the cosmological sense, because nothing will left, so it will be the end of everything. But for Bitcoin, the situation you described will be the beginning of its glory.
The Bitcoin holders stage is what we are passing through right now (if we continue our analogy with the Universe). Black holes are Bitcoin holders that don't spend and will not spend a single satoshi until they are forced to do so by external forces in the final stages of the Bitcoin universe. These holders only accumulate bitcoins, thereby making the quantity of Bitcoins available to everyone ever smaller. This leads to the price increase which potentially has no limit. What about subatomic units of a single satoshi after Bitcoin becomes insanely scarce?
But it will all most likely end in a Big Rip
