The question is: why would you want to know? the calculation will be based on a lot of assumptions anyway.
Or are you calulating when you would be a millionaire or billionaire ?
Instead of following news messages of people telling us bitcoin will reach $1 Million and stuff like that, I like to ignore them, sit back and just enjoy the ride

No matter what people / calculations are telling you... nobody knows for sure what will happen.
Look at it like a good book. You wouldn't read it if someone spoiled the ending for you.
Well The reason I would like to know is because I work from home
and I need a good sales pitch which i'm working on to get small business
hooked up with bitcoin payment system but I need to mathematically
show them in my sales pitch why is bitcoin a great payment system
even though the swings are so rocky and I cant figure the correct
way to do the math on this because of all the factors...but if I can
show them how the market will stabilize in the future with simple
division or multiplication i can probably bring the sales in.....
So i need to have my math down so I don't studder....
Like this The reason you know the payments from your
sales will be safe " even if the market fluctuates
day in and day out you will be able to pull money out daily or weekly
to safeguard your profits .....here is the math xxxxxxxxxxx blah blah blah and
bringing you a 45 % increase in sales yadayada yada so can i get you signed up
.............
so im tring to do the math on this thing can to fit it in to my shpeel ...
get it good
