Visa has a market cap of 63 Billion.
EBay/Paypal has a market cap of 44 Billion.
Citigroup has a market cap of 142 Billion.
ETC...
So these industries could fall and all of their wealth would be redistributed. As a whole we would be wealthier.
What you guys don't understand is that bitcoin is NOT a replacement to banks, payment systems, etc.
Bitcoin is the equivalent of cash in the mail, with extra security features.
Not true, or at least not the whole truth.
Bitcoin is simultaneously like:
1. Cash in the mail
2. Bullion mined from the ground
3. Physical commodity
4. E-currency
5. Paypal
Bitcoin is many things, limiting it only to money transfer is not very accurate IMHO.
Clearly this is invention of a genius, to say the true.
