I want to share my thought Why BTC Will Be Destroyed By Itself:
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
