I am looking for a reliable and low cost way to make loan repayments from Asia to the US. Are there any banks in the US that will acept Bitcoins?
"Translating" a Bitcoin to a US dollar is selling it. There are plenty of services that will sell your Bitcoins, including Coinbase, Kraken, and Bitstamp. You just need to find one that will do what you want with the US dollars after they've sold them.
