In 8 years, I am counting on the price to be either $100k+ or close to $0. As long as Internet is still around and no critical flaws has been found in the protocol I see that first number as highly probable.
market cap:
$100= 1,1bn
$1000 = 11bn
$10000 = 111bn
$100000 = 1,1 trillion dollarz | world gdp about 60-70 trillion dollarz right now
MV=PQ
Moneyz times velocity = "GDP"
Price per bitcoin = Bitcoin economy GDP divided by velocity (no clue what the velocity of bitcoin is atm)
Because money supply is fix the price goes up if the economy grows. Wait for Bitcoin economy to grow = PROFIT.
I think the price right now is too high due to speculation. But if we get more users and a better economy. Right now we have about 3 million standard client downloads.
Let's get that number to some more millions, suppose the Bitcoin economy will be 50 bn dollarz in 2 years, velocity = 5 = 10bn market cap = about $1000 per BTC.
I don't think Bitcoin will compete with the normal currencies much, it is a international internet economy moneyz. So how big is the market? No clue. Maybe one trillion? let's guess velocity = 10 = 100bn market cap = $10000 per bitcoin.
¥$!
