Now we have numbers with 3 decimal positions. This is good because it is easy to understand, and therefore there are more inclusion (kids, teenagers, grandparents, etc).

If we add more decimals, like 0.00000001, we will lose part of these users.

We solve the problem of inflation using only 10 - 20 steem, but the spamming will be present, and that means more costs for the witnesses.
