The price of bitcoins is going up no matter who accepts it. So long as money can be sent accross borders with out the fees Western Union charges it will continue to rise and gain popularity. Once the exchanges get their shit together, or if a big name money company gets involved as an exchange the sky is the limit.
Bitcoin will put Western union out of business within 5 - 10 years, then the other high priced money transfer services will be next.
