Debt adds to the risk of speculating. Sadly as an ex-banker I wonder about the real motives of the banks and I fear their motives have little to do with protecting their customers from losses.

How can the banks lose?

For example. if I mortgaged my house to borrow money to buy bitcoin and I bought Bitcoin in December and then bitcoin drops in value by half the bank still has my house for security if I go bankrupt. With a credit card the bank takes the lose if I can't pay back what I owe.
