Volatility is bad for merchants wanting to use everyday in their coffee shops, bookstores, etc. Volatility is bad for someone wanting to use this online purchases, ie, Overstock.com. Will they be adjusting the price daily? Hourly? Etc.

lololol. Bitpay.
bitpay is great but if everyone hitches the future adoption on these payment middlemen the big boys of visa/mastercard can just lower their rates to the same or a few cents more and adapt.. is bitcoin just going to be a napster that creates an iTunes?
the real killer app is if we do not need bitpay but are stronger because it is an option not a requirement
