I think good debts, this is because the potential for this year's bitcoin is very good and promising, especially if we take a long-term loan for example 5 years then the opportunity for profit is very large, the main key to profit is being patient and not panicking when prices drop.
in your opinion it's good, if possible you can pay well the installments that must be paid, but if you can't afford to pay it will add interest to the principal of the debt and of course it will increase the debt, of course it won't be useful. Even though the debt is for buying bitcoins which you can be sure can provide benefits after the halving period, if you make it difficult for yourself so that it causes bad debts with increasing interest, of course it is not recommended to do that.
everything is also adjusted according to the situation from yourself, how to repay it, if you can still afford it, of course it is very profitable and I agree with you.
