most people do already know how to use bitcoin but why they still have credit cards ? when you cash out , you will be using banks and you need credit cards to withdrew that money . sure you can use other cash out method but credit cards cash out are still easy and less hassel than others . too bad you already cut out you credit card , i feel sorry for your loss .
I have suffered no loss. Because of bitcoin I simply do not need credit anymore and have learned what a suckers game borrowing is. So I don't cash out or pay bank fees or credit-card fees or risk my identity, I buy it with bitcoin. No matter if the purchase is a house or a light bulb.
How are you paying for your daily needs or your bills?. You are surely not paying them with BTC directly. I know there is/are application(s) like Paytomat, offline users pay merchands with BTC and altcoins using the app. That you use such application or use a btc card, you are still using a 3rd party
