Edit: imo alot of people don't like the idea of billions and billions of coins
I believe this is more a matter of distribution. More coins means more potential for widespread adoption. I mean, if there are 100 000 people on the altcoin scene, that's the maximum. Compare with 7 billions (soon 9) inhabitant on this planet.
Coin amount means nothing when you can break the coin down to 8 decimal places. Its overall value that people care about. Does the same about of coin X buy the same about of product y?
I'm so glad you're taking the moral highroad and not bashing coins in their own threads. That could be considered hypocritical and desperate.
