You're correct. I'm simply replying to his statement that there's no value proposition in bitcoin to consumers. My response is that it can easily replace a company worth $8.7B, thus showing it has consumer value, not that bitcoin will be worth $8.7B if it replaces Western Union.

That's completely true, but it's also true that if that day comes and Bitcoin is so entreched in the global marketplace so you can exchange it in Burkinabe villages, then it will be worth 100x today's price (especially when taking bubble effects into consideration). For some people in some situations that can be a rational bet to make.

Yes, it has a long way to go, but it's off to a good start. I doubt a significant portion of Western Union transactions are to ultra-remote locations, but I could be wrong.

The point of bitcoin is that you don't need FDIC protection. You need FDIC protection with a bank because the bank isn't required to hold enough reserve to cover its deposits. If there's a run on the bank, and everyone wants to pull their deposits out, and the bank is insolvent, then the government guarantees to protect consumers by printing more money (inflation) to fulfill the bank's reserve requirements.

With bitcoin, you either have it or you don't. You can run your own bank, as long as you know how to safely store a private key.
