RE: How viable is Steem as a currency as the Steem network must constantly create tokens to reward bloggers and enable votes (causing lots of inflation)?

Huh? All tokens have inflation. Bitcoin has inflation. Its around what... 3% i think.
Its just that the inflation is distributed differently.
In bitcoin only miners get the inflation, on Steem its distributed to everyone that contributes.

Once bitcoin stops being mined fees will go through the roof. Low Inflation is good and anyone that thinks otherwise knows nothing. Those that use the fact fiat is inflationary as a bad thing are idiots. Fiat has other drawbacks but inflation isnt one.
Its actually one of the reasons we live in the wealthiest time in human history.
