Does it make sense to use BitCoin to transfer money to yourself internationally? If you have a bank account in the US and an account in the UK, and you want to move money from one to the other, is Bitcoin a sensible way to do it, or are you better off using TransferWise or just doing an international wire transfer?
While in the US last year, I sent money to myself in Europe that way once, because it was significantly cheaper than using the legacy banking system.

I think it mostly comes down to whether you have easy access to a Bitcoin exchange from your bank account in the US and what amounts you are trying to transfer. It also depends on how urgently you need the money in the other country, and which country you currently are residing in.


Alternative 1 (if in UK): Use your US credit card to get Pounds from the bank, deposit those in your UK bank.
Advantage: Fast
Disadvantage: Currency exchange fee, fee for using CC abroad, (Deposit fee, if you have one)
Alternative 2: International Wire Transfer
Advantage: No manual involvement
Disadvantage: Takes several days, expensive (~$50), get lost sometimes
Alternative 3: PayPal
Advantage: Very fast, independent from residence
Disadvantage: ~3% exchange fee, % transfer fee, has to be withdrawn to Bank account
Alternative 4: Money transmitter
Advantage: Fast
Disadvantage: Needs to be picked up and deposited, expensive I think
Bitcoin:
Advantage: Can be cheap
Disadvantage: Takes a few days, manual involvement
Procedure:
• Consider buying Bitcoin locally if in the US, else buy Bitcoin from Exchange or Coinbase (each takes a few days until it is cleared, I think)
• Send Bitcoin to your account at an exchange in Europe
• Trade Bitcoin for national currency
• Withdraw to Bank account (usually a small fee applies).


Personal experience
Back when I did that last year, I was able to buy Bitcoin at a Bitcoin Meetup at Bitstamp spot-price. I transfered those to Bitstamp, traded, and ordered a withdrawal.  

I had a confirmation that the money was headed to my bank account within 30 minutes, it arrived two days later. I actually made a few dollars on it, because the price had slightly increased between my local trade and the trade on Bitstamp.
