Bit Coins are actually more real then the US Dollar. Sure we get a paper or coin note stating that this represents so much. But at least bit coin is connected to something in limited supply thus needs to be shared.
I've never understood the logic behind statements like this. There are an infinite possible number of cryptocurrencies. A cryptocurrency is nothing but a mathematical algorithm being run on a lot of computers. By its very nature, it can't be in limited supply. Saying that Bitcoin is valuable because it's scare is like saying that digital music or digital video must be valuable because they're scarce.
Any one, at any time, can create his own blockchain and create a Bitcoin clone. After that, all he need to do is persuade other people to adopt his blockchain, and a new standard has been created, with the originator becoming "wealthy". In fact, I suspect that this idea may suddenly occur to the operators of one of the big idled mining centers over the next few months.
And before anyone says, "But Bitcoin was first!", let me reply, "Friendster and MySpace".
A Bitcoin is a unit of account in a specific ledger. The number of units of account in that ledger is finite. Additional ledgers can be created, and have been. But the value of units of account in those ledgers is not equal to the value of the unit of account in the Bitcoin ledger.
It's a little bit like comparing seats at a concert. Yes, we can put more seats in the back, but they are not valued the same as seats in other sections. We can create more seats, but we can't create more seats in the front row.
