This is great news for sure. I do wonder, however, if some will be reluctant to try it b/c of the volatility in price. If price drops 5% before one can cash out to fiat, this effectively creates a high transaction fee. Of course, price could also go up 5%, effectively giving one a profit on the transaction. It's good news either way, I'm just wondering how quickly it will catch on. But eventually I think this will be a big driver for Bitcoin.
Easy fix: convert to fiat at time of BTC transfer.
I was assuming conversion to fiat at time of transfer. The point is that Bitcoin is sometimes so volatile that price could change a few percent during the time it would take to get enough confirmations and convert to fiat. Granted, it is somewhat unusual for BTC to be this volatile, so I don't think there is major risk here. But I was wondering if the perception would be that this is a risk, and make some reluctant to try it.
