Every day Lot of people ( all of the Worlds) mining BTC it mean every day/Week/Year More BTC will be Injected to the Netwrok and it mean BTC abundance Will be increased and than Price will go lower and lower until 1$ probably.
Example:
Gold, silver and platinum are rare, thats why they are Expensive, BUT If Gold abundance was the same as Iron than Gold never was Expensive
I agree with you that BTC supply increases but for sure BTC demand also increases day by day. I don't think it will be destroyed by itself BTC will still be heal and develop and the network performance will still be updated and will bring new and will satisfied the peoples needs.
