But if it happens a hundred years or two from now, it must of course be good for Bitcoin. Bitcoin must already be worth hundreds of thousands of dollars by then.
uhh Bitcoin will be worth hundreds of thousands this decade and next decade, and almost certainly leave that range for the millions in the 2040s, not in a century or two.
In a hundred or two hundred years from now, assuming something doesn't happen to make bitcoin stop its growth and reverse course, Bitcoin will definitely be worth tens of millions of dollars. There is no doubt about that.
Some math for you:
100 years of let's say 3% inflation, with no actual real value growth for Bitcoin's value, from $50k would take Bitcoin to $960k. That's just inflation, 2024 $50k = $960k in 2124 with 3% annual inflation. With just 11x real price growth (which is likely in the next 15 years, not 100 years) Bitcoin would be worth $10.5 million. Definitely Bitcoin will be worth in the tens of millions of dollars in 2124, and the hundreds of millions of dollars in 2224. The thing is that the Dollar will be nearly worthless compared to today.
