More coins, more liquidity and less spread in price. I don't know how some people can't see that.
1B would be much better but of course majority decides.
More coins, more spread in price unless you move to a lower base market (like LTC)
That's because more coins at the same market cap means lower sat price per coin. And as you approach single digit sat prices, spread increases
At 5M we would start with 5 digit sat prices (assuming beginning prices at roughly cost)
I really can't see liquidity as a problem in any crypto. 5M is no different than 500M with 6 instead of 8 decimal point. And I don't see the 7th and 8th decimal point becoming significant anytime soon even for bitcoin, let alone any other altcoin
