Which, by the way, are already much cheaper than transferwise at 1.4%.
With bitcoin, hell, I dunno. https://www.quadrigacx.com/account-funding-withdrawal this wants me to do a bank wire to avoid fees which I can't do online, it's one of my major complaints how the simple transfers in Europe are missing in Canada but I digress. If I use interac online, ding, 1.5%. Then I get bitcoins which I need to store securely, send them and it seems https://cex.io/fee-schedule#/tab/trade there are fee schedules expressed in a language I sure never heard of and then my brother also needs to find an exchange to get EUR out of. Seems hell of a bother to me to save a little money. I am not sending 10K, good for you if you do, I am sending 1000 EUR a time or so, we are talking of saving a few EUR. No way.
As for transferring money, Transferwise is leagues ahead in usability when you consider that the sender has some sort of currency and the receiver wants currency (and bitcoin is not a currency, no matter how hard these Ayn Rand types insist, not without a nation state backing it). All you need is a name and an account number and the UI is super friendly and the transfer is cheap.
