Some beginner questions! How many ADA tokens/coins are there? Who set the amount? Are they divisible?
So why was 45b chosen as the max amount?
The smallest unit is a Lovelace = 0.000001. I wouldn’t read too much into total supply figures of any coin. The artificial scarcity doesn’t matter as much as people seem to think. Apparently they took the high figures of the yen into consideration.
