Great idea! I’ve done this before too.
If you have credit cards, use the cash back you’ve accumulated to buy Bitcoin.

Fortunately I don't have debt and don't do credit cards... the only money I put into the bank is the bills I pay.
But I've heard of this ... I just have to do it manually 😕
Good for you! 👏🏻
Credit cards can be a powerful tool if managed correctly. I generally pay mine off by end of month to avoid interest. The cash back hack is a nice way to get about $20 to $30 in Bitcoin per month on the bank’s dime, not mine.
