Question:
How did they decide a max supply of 21 billion coins?
7.6 billion people on Earth and 21 billion coins, only a small group of people have access to internet, have knowledge of internet/cryptocurrency, have money to invest etc, new crypto born everyday etc..
A lot of factors that reduce the number of people could potentially invest in BTCZ.
I think 21 billion coins is a way high number.
Is there a method so BTCZ community can vote it?
The OP likely was looking to the future, not as much the here and now. Imagine a day when everyone in the world
does have access to crypto and uses it in their every day life. When you think of it like tat, 21B doesn't seem like much.
