A balanced view is that all the articles hold some substance. But the technology is more at threat through its own community than any external force. One question that I don't really understand is how can the total supply of BTC serve its own growth. If the market cap reaches the same value as gold for example - how long before one Satoshi becomes too large a divisible unit to be useful? Can you divide Satoshi?
Isn't the greater problem that the total market cap of bitcoin is always going to be 22 million? In other words, the single bitcoin I own will always be worth 1/22M of the entire market cap, regardless of how much it's used. And I only own one. There are lost of people out there who owns thousands of bitcoins. 1000 bitcoins is 1/22k of the entire market cap. How could this be sustainable?
Consider that wealth in the real world also accumulates in a non gaussian distribution.
