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.
I understand your point but it seems more like a non profit company like this, let me explain.
http://www.internetworldstats.com/emarketing.htmIt took 22 years (1995 to 2017) for internet to reach half of population. There is half of popolation that doesn't have access to internet.
It could take 20 years or more for crypto to reach half of population.
After reaching half population doesn't mean they will all use them, big corporations are preparing to battle crypto (big banks).
They will do whatever it takes to maintan the control.
New crypto born everyday and for a crypto to gain interest it not only the technology and community behind it, it is also its price that makes it interesting.
If BTCZ could find a way to reach an interesting price (maybe lowering max supply/burning coins) then things could become easier in the beginning and could have secured the future.
Just my two cents.
