We need local businesses, or even corporations to start adopting Bitcoin! When this starts happening at a large scale, I think we'll see a tipping point in Bitcoin adoption.
"To calculate the exchange rate for US Dollars, we pull up-to-the-minute BID prices from three exchanges. We take the 2 that are closest together and toss out the third, so that a bad feed from one exchange will not affect our calculation. Of the 2 rates that remain, Bit-Pay uses the highest BID price as our exchange rate. "
Companies don't end up changing prices every minute. Gas stations, for example, are prohibited from changing prices too frequently in many states.
A proper solution has to provide more than one minute of price stability. BitPay doesn't provide longer term price stability.
If all illicit/immoral/illegal transactions happened in BTC, the likelihood that "proper/legitimate" transactions happen in BTC is higher.
Because: - now people know how to use BTC - they are comfortable spending BTC - they have some BTC on hand (that they may typically spend on illicit goods)
