I'm critical of BTC but I think this is true. It is a technological breakthrough in this regard. I'm not entirely sure that the transaction costs are so low that most people would prefer to do it via BTC and not through a third party, however, especially if remittance services start competing by using similar technology in their backends. There are specific instances where people do not have remittance services available to them -- getting money across some borders, completing illegal transactions, etc. For BTC to be a mainstream money transfer method, however, it will need to be obviously better than just doing it the old way -- paying a 3rd party to clear the transaction. It's an elegant technological breakthrough in search of a killer app, I think, and that killer app can't just be illegal or extralegal transactions. If that's all it ends up being, governments are going to crack down even more than they already have.
