I'm thinking about taking out a personal loan from Itaú or Bradesco to put into Bitcoin and Ethereum. My salary's decent, but I'm unsure if it's really worth it considering the interest rates they're charging now in 2026. I've lost money on crypto before so I'm kind of hesitant about it.
Don't do it, honestly. Personal loan interest rates are astronomical (like 40-50% a year or more) and crypto is way too volatile for you to be betting money you'd have to pay back with interest on - you've already lost money before, so you know how risky it is.
You're right to be worried, especially since you've been through this before. Taking out a bank loan for crypto is really too risky - it's not that the interest rates are necessarily 40-50% (they vary a lot depending on your profile with the bank), but even at 25% per year, if Bitcoin drops 30% you're already in the red and you still have to pay all that back.
The real problem is you'd be borrowing money to make a bet, and betting with money that isn't yours is gambling, not investing.
If you want to get into crypto again, invest only what you could afford to lose without losing sleep - and then yeah, without a bank middleman charging you interest on top of it.
I've seen people lose money this way and the worst part is when the bank bill comes due while crypto is tanking, then you're actually stuck with debt. The interest rates are pretty heavy, yeah, but the real problem is psychological - you make a bad decision out of panic when you're seeing red in your account and knowing you've got debt to pay, so you bail out of the investment at the worst possible time.
