similary,gold is not control by any entity.
You cannot really compare the gold Market to the bitcoin market; if you go that way, then there is a very big difference. During gold trading, third parties are involved, and sometimes your identity is revealed unless you still use a third party to purchase the gold. In a gold transaction, there is no privacy, and perhaps you can't hold gold without one person's consent, but for Bitcoin, you can do so without your identity revealed. Talking about Bitcoin as a digital gold, sure, I used to agree to it before, but I think something else should be used because already gold has been introduced into the Blockchain as a digital gold. There are some digital currencies, like Kinesis Gold (KAU), that are backed up by real gold. So,I think Bitcoin should not still be referred to as the digital gold because it's not backed by gold.
