Bitcoin is inflationary until the year 2140, and assuming no fork changes that sooner.

If you actually understand Satoshis algorithm and history you'll take notice at how the supply was intended to benefit the first few users to run the software during the brief phase of hyperinflation and production for minimal work, while later users are punished merely for running the same protocol and offering the same computational work equivalent to prior users.

If you consider how easy a linear curve could have been chosen by Satoshi instead of the reverse log curve, you'll understand the manipulative nature of how Bitcoin exploits new users.

The supply inflates every 10 minutes, this by definition is inflation.
