Not sure if it is your 2nd account (you registered 5 months ago), but those who are here for ever remember that people was actually interested in the technology and the "alternative to fiat money" for real before the GPU mining fever of 2020 or before the rally of 2017. Back then there were other problems, like trashcoins forks everywhere to get a quick buck, but those coins don't exist anymore.
The inflation is there to incentivize spending (using) currency.
Looks for the story of central banking, it explains everything. Devaluation is there to take away purchasing power of the people and concentrate wealth in few hands.
