As a disclaimer, I've bought some bitbars on
Cryptsy. But I bought them because I think they have the potential to be valuable. And, I actually believe they'll end up being worth more on a one-to-one basis than bitcoin. Here's why:
1) Scarcity. There are less than 8,000 bitbars in circulation and that growth rate is slowing.
2) Current value. Bitbars are already the second-most expensive currency trading on Cryptsy (current value: $22+).
Ultimately, there will be 21,000,000 bitcoin in circulation. That means each bitbar is 2700 times rarer than each bitcoin. In a perfect world (i.e. if demand for bitbars matched demand for bitcoin), that would mean that each bitbar should be worth 2700 times each bitcoin. At the current asking price for bitcoin ($823), we'd be looking at a value of $823*2700 or $2.2 million per bitbar!
Of course, I doubt bitbars will ever become as popular or widely accepted as bitcoin, but they will remain important in the crypto-currency trading space thanks to their scarcity. Why would I want to invest in a currency that's going to mint hundreds of millions of coins when I can invest in one that mints thousands?
