....but more important to understand that all scenarios won't do harm to Bitcoin.
ALL scenarios ?

It takes only one scenario for Bitcoin to be kaput!

People want to believe that Bitcoin is immune to every threat to feel more comfortable, but it's not true and never will be.
It is a constant arms race, and Bitcoin will need to hard fork every time a new cryptographic weapon emerges.
The day it stops hard-forking-or fails to do so in time-it's game over.
If you believe otherwise, try running Windows 98 as a commercial server and see what happens.

Many people still believe there will only ever be 21 million Bitcoins, not realizing how unsustainable that is-and that this, too, will eventually need to be fixed through a hard fork.
Mainly people who live in an echo chamber called /r/Bitcoin, where I would get banned within seconds of posting such a "fallacy".
How can you even say such evil words. I can’t believe you. In these holy grounds, in satoshi’s home. What a disgrace you are.
Bitcoin is the one true god and satoshi is his prophet and in no point of time there will be more than 21 million bitcoins in existence. The holy book says it who teh fuck are you to challenge it?
If you don’t believe it, I don’t have time to waste on you.
