Not really. The Bitcoin economy's problem is fundamental as mentioned in my post above yours. When BTC is mostly hoarded and stored then Bitcoin's economic growth is impossible. But its value will rise, that's for sure, since it is mostly treated as an investment vehicle (ie a commodity like gold) rather than a currency.
Totally agree with this. It is not necessarily that openbazaar is lacking, it is due to the fact that people are hoarding btc and it is primarily treated as an investment at this time. This is just the early stage of the technology and is to be expected. When the price stabilizes and more mainstream adoption occurs then openbazaar will take off. The concept of a decentralized marketplace is relatively new and is very awesome.
