Bitcoin is proving to be extremely strong, practically "immune to death". If you look at Bitcoin Obituaries, people among the most influential and powerful in the world (let JPMorgan CEO be one example) have been unsuccessfully trying to bring it down. Even Hearn tried to destroy it and, despite all the incredibly negative promotion worldwide, Bitcoin's price went down a little only to (slowly) get back. If not even one of its creators was able to kill it, who will?
Well 'you can always be replaced' is what i think.
nothing is permanent in this world. what different is a virtual thing.
Bitcoin is limited let me tell u. many of them lost many of the stolen and no one can mint more. once that is done what will you do. alt coins with the highest potential will work.
once the bitcoins hype is over the alt coins will rise.. and that i think wont be global.. maybe regional .
why on earth would we ever go back to regional currencies after we have made a global currency?
It's not logical to go back like that to something that is worse.
