@luke 1 billion was just a joke lol. Seriously though, what's your "real" prediction for a relatively sustainable exchange rate?
It's almost retarded to try to predict the future price of bitcoin nowadays... Too much is changing from day to day, and we still don't know everything that bitcoin is capable of yet.
Back when I thought only Western Union and Paypal were in trouble, I'd have said "Take those two companies transaction volume and add it to bitcoin's market cap with a little extra from displacing gold."
For those interested, this amount would affect bitcoin's price something close to this: (Derived by dividing by current market caps by 21 Million eventual coins for simplicity)
100% of Current price of a bitcoin: $800
100% of Paypal & other web transfer systems: + $7,100
100% of Western Union and other Remittance systems: +$20,900
5% of the planet's Gold market: $17,500
--------------------------------------------------------------
Future price of a bitcoin: $46,300
...So I would have said each bitcoin would be worth just shy of $50 grand when those industries & 5% of the gold market are replaced.
But that's just not taking into account the MAJORITY of industries that are actually going to be displaced... Now that I understand bitcoin better, it's clear that there is no line in the sand at the edge of those industries and the start of others that won't get crossed.
As crazy as this sounds, western currencies are headed downhill quickly already thanks to fiat bubble mania, and bitcoin is prime to receive these people's wealth in mass... Cyprus did show us already that it could do so.
Who's to say it's impossible that bitcoin will hold over half the world's wealth one day? We just don't know. If it does it'll go to a several trillion dollar market cap meaning several million dollars' worth per coin. (As the dollar declines greatly of course.)
But right now looking at just the industries that are very likely to get displaced by bitcoin (a ground-up view rather than a top-down view) I'd say it could easily go to $200,000 per bitcoin in a decade... Depending of course on the fight that governments give it.
So, somewhere between $200k and $2 Million would be my guesstimate for a successful bitcoin 10 years out.
Of course $0 is possible too, if bitcoin is attacked successfully, but I strongly doubt that the price of bitcoin will stay somewhere inbetween the two numbers after a decade.
