Bitcoin supply is limited. So far so good.

The supply of alternative, competing cryptocurrencies is unlimited. Very bad.

Imagine a world with dozens or hundreds of competing cryptocurrencies. They would each have minimal value.

Bitcoin doesn't look like a hard currency solution to government money printing. It's the ultimate soft currency.

Bitcoins may have a brief moment in the sun as media coverage inflates a bubble of interest. But I doubt it's sustainable.

I'm sure this simple observation will grate with many of you. Sorry.

Spare me your rants. Share your solutions.
