Total world money supply is ~70 Trillion 2013 USD. 21 million BTC.
70,000,000,000,000 divided by 21,000,000 = 3.33 Million USD per coin.
Max value of BTC is 3.3 million USD each. If it were to entirely replace all fiat on the planet..
What if Bitcoin became the "world economy" but in the sense that you could use it in every country in the world, side by side with that given country's fiat?
You travel to singapore, you can convert to Singapore money or you can use bitcoin.
London? Bitcoin.
Bitcoin is used by everyone, everywhere as the "alternative" currency that is now global.
Would it really need to *replace* fiat to attain that market cap and per-coin value?
If it were to become *the* world currency, even if fiat currencies remained ... could it match the market cap while remaining side-by-side with fiat?
