Well I have no idea what BTC will be "worth" - tomorrow or next year!

I just recall what Warren Buffett says: "Consider the Market to be a madman who offers to buy everything you have or sell you all you will buy at some totally random price! You only get into trouble when you think that this madman actually knows something."

BTC is a "medium for exchange" and no different in concept from things like the Yap "stone money".

It does have a certain utility value, but NOTHING that carries significant wealth can avoid some very determined and very smart attacks.

To me the real question is how well will the BTC mechanisms stand up to real and well funded (>US$100M) attacks.

The Iranians thought their nuclear program was secure until STUXNET (see the Synaptic report)!

Is BTC even THAT secure?

WHO KNOWS until the attacks actually happen and either succeed or fail.
