We could say there are ONLY 21 THOUSAND bitcoins, and have them subdividable like 11 decimal points. Just to put a perspective on the arbitrariness of how we define the limit.
Actual BTC limit = 21000000.00000001
Could just as easily be: 21000.00000000001
Or even: 21.00000000000001 (only 21 bitcoins in existance! lol)
So, we could say "21 thousand bitcoins ONLY!" But does that mean there are only 21 thousand bitcoins? No.
They're all the SAME
QUANTITY of UNITS allowable. Pretty arbitrary really.
Just food for thought.
you can change the base of Bitcoin to whatever you like and it's the same.
A great way of putting it.
Right now, I bet it would be beneficial to move the decimal place a few points to the right so that people feel like they're getting more bitcoin. That psychological effect is a big one.
As an uninformed public I'd much rather have 200 microbitcoins (or whatever) worth $200 total than 2 bitcoins worth $200 total. I bet it would lead to a lot more adoption purely on the psychological implications alone.
