Yeah, but I am most interested in the next 10-15 years....2045 is way too far for many people, including Michael himself, perhaps...he would be 80 then (much younger than W. Buffett, though).
If someone interested, I've got essentially the same conservative number ($3 mil) assuming 25% growth in the next 10 years and then 15% growth for 11 more years.
This "assumes" that bitcoin slows down it's appreciation. Most people agree that it would eventually happen and the only question is when.
I would be totally fine if btc instead kind of reached the very high plateau at, say, $3-5 mil per in 5-10 years and then just oscillate with a 7-10%/year upward trend.
Last 5 years were roughly 48.2% yearly appreciation and the 5 years before that-75%
That said...and just playing with numbers... if you project the slowdown linearly from today's prices (comparing an exact point 10, then 5 years ago and a point 5 years in the future-July 26, 2029, then the 'theoretical' yearly appreciation number (average) in the next 5 years is projected to be 30.97% or 3.85X or $262,236-kind of on the low side, but it is what it is.
