With regard to bitcoin inflation isn't really the right term, because it has  capped supply of 21 Million (which we won't see in our lifetime). but by going with wat the definition says:

Inflation (noun):

1.
the action of inflating something or the condition of being inflated.
"the inflation of a balloon"
2.
ECONOMICS
a general increase in prices and fall in the purchasing value of money.
"policies aimed at controlling inflation"

I guess really neither apply? cause Doge has actually increased in value since its inception
