Before e-gold was shut down, it has ~$600 million in their accounts. In order for Bitcoin to become a similarly sized threat each coin would have to be valued at $82US.
But, e-gold had no mining aspect, so all the $600 million was actually paid for, no? And the actual amount of bitcoins *bought* would be much less that total value of all bitcoins, because most of them were mined and parked somewhere.
What was the typical usage for e-gold? How many vendors accepted it? In what industries?
