I mean if I transferred a billion and my bank made a mistake, I would not lose any money. Make a typo in your bitcoin transaction, and you're screwed.
I think that they are making the point that they actually are free of charge. Fees for moving money at banks are negligible. They might not actually be entirely free, but wire transfer fees are ~$20, and I've moved a million dollars this way before. I don't know if there's much of a difference between a million and a billion in this context.
That's right.
An "on-us" transaction, one that simply requires RBC to update its database by debiting funds from RBC customer A and crediting them to RBC customer B, is free. (If your bank is charging you for that, switch banks!).
A wire transfer is more complex than an "on-us" transfer because it involves two bank database. RBC has to debit its database, and Bank of Montreal has to credit its database, and the central bank is usually involved as an intermediary. This often involves a wire transfer fee.
There's a billion dollars difference between a million and a billion. You can't just plop a billion dollars into your checking account. It's part of a hugely complex context (how would you even accumulate a billion dollars to deposit?)
Not really, bitcoin addresses have checksums.
In India and Australia, the banks just use the account number not the name. If you screw that up its completely your fault. The bank might help but its not obligated to do so since you accepted these terms and conditions.
