I have a bank account and some credit cards with just enough to pay the bills. The rest are in crypto. It's more convenient and you do build up a good credit rating or credit score if you pay off all your cards or keep utilization below 5%.
When you guys talk about credit utilization.... do you mean something like deferring payments instead of paying the bill at end of month?
Never knew anyone that would do that. Looks suicidal considering the extreme interest. I would expect someone having to resort to that type of credit to be on the verge of bankruptcy already. Same with the people leasing or buying cars on credit (although I know some of those).
