Currently worth $70 Bn, Is this a lot?
Personally it seems quite a lot for a fairly untested currency.
US gold reserves currently worth something like $300Bn, the largest in the world (though it's no clear if anyones checked its there). All this is less than a company like Google but still $70Bn is a lot of money.
For the bitcoin price to rise a lot of money would have to flow in. Right now it seems like every grandma and her dog is being persuaded onto the bitcoin bandwagon. Is this not a sign of an impending crash, in which those at the bottom of the pyramid get burned? Is the bitcoin rise sustainable? Where will the money be flowing in from? Will shops have to start selling bitcoin investment scratch cards over the counter to keep the price rising?
I'm keen to head from people who can make arguments based on fundamental economic principles, either way.
I'm sure there is room for the market cap of bitcoin. As you are saying the gold is worth 300B in just USA market then just imagine how it is worth in the whole world. That's a lot of money and if that can come into gold then I'm pretty sure it can come into all new crypto currency like bitcoin. Gold is being traded since decaded of decades and that's why it has that much supply and investment. Imagine bitcoin reached this much in just a decade so there is still big time for the bitcoin to get into action and make the world dance.
