If considering the really large numbers for the entire crypto market and all its possible innovations and growth possibilities then I got to equate it to a
traditional weighing scales in an image of balance. Its true trillions are unlikely but also value will not shift to crypto exclusively without value elsewhere becoming lower.
So what I mean by that is the dollar value itself can drop, in the last year its fallen by 10% and this has no doubt helped raise the nominal price for crypto and BTC. A 10% fall in dollar alone would make every BTC priced in dollars, also 10% worth less.
However a drop in dollar value likely indicates that a reduction in US dollar as world reserve currency is happening. As all crypto can be used globally easily across borders, its very much an alternative option and likely to gain from dollar decline.
This is why 100,000 for BTC can never be said to be impossible. I also expect $200 per barrel of oil at some time in the future even while I believe the overall domination of oil in energy usage is dropping. The general reason is FIAT currency is weaker now then any other time since Nixon was in office and that's a fair old whack of time, a big trend break leads to vast changes possible. Its a tide change, everything I mention is a known possibility but like the tides people can still be caught off-guard by the breadth and magnitude of changes in the world. It makes more sense to recognise alteration will occur then believe one country or even its partners continues to underpin the world reserve currency indefinitely.
Probable, possible, maybe but dont imagine never. This is the biggest story of this generation imo as capitalism is paired to freedom and democracy it can alter the lay of the land we walk on.
