This isn't a bad thing imo, using lines of credit to buy Bitcoin is not a good idea.
Stockholm syndrome with banks huh?

Why would Bitcoin be different to any other thing you can pay with your credit card? Don't be so naive, they are not trying to protect consumers here, just their own filthy interest.
I'm under no illusions that banks give a shit about their customers but when masses of people who probably dont understand what they're signing up for use money they don't have to invest in a rather volatile market it's not going to end well.
If everyone just invested what they can afford to lose we'd have much less panic selling and regret.
