Hi,
I have the feeling that the Bitcoin price of 6600$ is much too less. I think the price should be more than 100,000$.
Everybody speaks about Bitcoin, but there are only 16 million of coins.
Limited supply is the backbone of increasing Bitcoin price. You can't say that because of limited supply, everyone can't own Bitcoin and that's why price is less. Read about demand-supply law and you will be more clear.
And in my opinion, there are a huge number of people they own bitcoin.
So, I think that many people own "Bitcoins without having the private key".
Do we have already virtual coins in the market outside of the blockchain? Are the Bangsters back?
Was Bitcoin not created because of this?
Having private keys or not don't imapct the supply of Bitcoins. In case of web wallets and exchanges, users no doubt only have representative value of bitcoin in their wallet and not real coins but those values aren't manipulative and web wallets or exchanges do have those Bitcoins in their cold or hot storage.
Now we have already CFD contracts: You can bet on the price of bitcoin without having the coin.
CMD or Futures market having nothing to do with Bitcoin and its price.
You have coinbase, I am not sure but you cannot export the private key. Is this correct?
Correct.
Many people have bitcoins on the exchanger, but they don't have the private key. Have all the exchanger really the bitcoins they trade.
Or have they only enough bitcoins for some people to transfer to a bitcoin address. But what would happen if all exchanger users transfer the
Bitcoins to a Bitcoin address. Have we then again, the message the system is at the moment not available?
Again same thing, exchanges do have real Bitcoins with them equivalent to what users have on their representative wallets. There is constant influx/outflux on exchanges which ensures there is symmetrical cash (Bitcoin) flow on system. Which ensures in the case all users withdrawing Bitcoins, exchanges have enough to pay them all.
