I tried to sell some products for bitcoins and guess what, nobody buys! This may be due to the prices which are a little bit higher than the price in dollars, but it may also show that bitcoin is not preffered for buying goods. So perhaps it will remain only an economical tool for the darkest corners of internet and a speculation area. Therefore, the bitcoin could not have a very bright future.
To me it's an expensive hassle to obtain BTC and through most paths I have to deal with entities who I don't trust (potentially including the likes of Dwolla, the various Bitcoin exchanges, my banks, and my government who is almost certainly logging all of my financial activity.) To top it off, I am concerned that it will become even more difficult to obtain BTC going forward so the supply I hold currently exceeds the 'face value' in my mind. That is why I have little or no interest in spending BTC when there are options.
Am I a bad person for failing to support the nascent economy? Probably. OTOH, I've not yet been ripped off either. I consider the USD<->BTC hassles which currently exist to be something of a blessing insofar as it gives the solution an excuse to fail at the exchange level. Perhaps the solution would not be so rife with bad apples absent the roadblocks to use which are currently in place. I actually don't really believe that in a major way because the roadblocks are not that significant and the failures have been mostly associated with user error (aka, ignorance, greed, false mapping, etc) in my opinion. But it makes a good story at least.
