If btc reached just one tenth of that value in the next 6 years they will have to grow with atleast $1 every week on avarage.
To reach the same value, within 6 years the price would have to grow with $2 each day, on avarage.
Ofcourse such growth would not be linear but go in waves.
Thing is, thinking in dollars per week/day doesn't necessarily make much sense.
A $1 gain when the price is $1 is MASSIVE at 100%. When the price is $1000, a $1 gain is insignificant.
At current ~11 million coins, the price would have to be slightly over $9000 to be at $100B market cap. In order to get there in 6 years, the price would have to increase 257x, or about 2.52x a year (that's 152% yearly growth). That translates to 1.08x every month, or 8% growth per month, which is about 0.26% daily growth.
Those calculations are done with the assumption of 11M coins in existence, I didn't calculate inflation in. With that included, the growth would have to be somewhat faster.
If you include money supply inflation, the price growth required is slower not faster.
You're right of course, fixed. Doh
