So basically this company, Conio, has a multisig (3keys wallet) and they provide such service to a bank, Hype by Bank Sella? This is unbelievable! You are telling me that a bank in Italy allows people to buy bitcoin so easily! That's crazy
It may sound crazy, but it's reality

You can do it directly with the Hype app, which is the leading challenger bank in Italy (1.3 Million users). It's been live in production since March through the integration with Conio, and it makes extremely easy to buy and sell (real) Bitcoin in Italy.
You may read it a bit more here, when we announced the launch:

Yesterday Paypal announced you can trade Bitcoin CFD on their platform, abiding to AML laws in a very safe and conservative way, and Bitcoin price popped.
HYPE + CONIO provided a real Bitcoin Trading platform integrated in a bank home banking platform and anyone barely noticed.
What is this? better marketing? Or the sheer power of user base numbers?
Sorry, that is off topic here...
