I think Bitcoin is dead as a general payment service, but it has a tremendous future as a store of wealth. It really has become "digital gold". It is also a great way to pay for digital assets that have a reasonable value, and that includes domain names. I hope that more people will be prepared to pay for names using Bitcoin.
I'm getting rid of fiat based assets, and Bitcoin is one of my investments at the moment. The price is a bit volatile, so I wouldn't suggest putting all your money into Bitcoin, and you certainly shouldn't borrow money to buy Bitcoin. Remember, when the banking system is shut down, and there seem to be a few trial runs for this that I have seen, you will still be able to buy and sell with Bitcoin.
