Nice credit card company! Where can I get an account like that?!! Mine demands proof of fraud and internal review before they’ll try to reverse a valid purchase.
Actually, Transferwise (my favorite service!!) is not quicker than BTC for international and Bitcoin is SLOW (I said so above – it was never meant for speed – Confirmation takes 60 minutes!). ETH is slow too, but it still transfers value in 1 – 5 minutes, and then there are the protocols like Ripple and NEO which are much faster.
