Again, you are missing my point. Because this fluctuates so wildly, anyone who wants to use Bitcoin IS an investor.
Lower fees....debatable. We just moved from from $166+ to $157 in no time. That transaction just became 5%+ more expensive if I purchased @ $166, not including spread and BitPay transaction fees. Actually, while I'm writing this we are now at $153.....so much more expensive than any CC fee. This is the foreign exchange risk I'm talking about. $166 - $153 is almost 8% in a matter of minutes.....plus 1% for BitPay and 1% for the spread (now at 1.5% due to volatility).
Take the 24-hour weighted average. Or 3-day weighted average. Is what regular people should use. Also, this volatility won't remain forever. Merchants don't like volatility, even when converting to USD, so at least they believe it's temporal.
More potential clients.....are you finding people that only use Bitcoin and not fiat???
Exposure to a huge community.....are you finding a community that exists entirely outside the fiat landscape???
I do use fiat, but as I said earlier, there were several potential purchases that I didn't do at all because of lack of merchant support. Having a bitcoin option makes me more prone to spend money.
This is the chicken and egg problem. Your statements are like critizing creating e-commerce 10-15 years ago: the public was too small, but we needed those early merchants to keep the ball rolling, get more people used to do online transactions, hence geting more merchants doing e-commerce... etc.
