I hate the whole publicly traded model of companies. I hate capitalism. But have to engage in trading stocks (I mostly do Mutual Funds and a small quantity of direct stocks) so that my money doesn't lose value by sitting in a bank or cash.
Same thing with credit cards, don't like taking loans and getting marked on a centralised list for that but it's a safer option than using your own money.
Fortunately I don't do crypto so that's a plus.
Yeah pretty much how I use them. But I'm pretty sure they earn money from every transaction or the whole thing would not exist.
