in my opinion, loans are a good way to get profits, especially in the world of commerce.
bullish will provide benefits, but, sometimes we must always see and control market volatility. and that is not easy.
Loans can be a good way for some people who lend their money, but for the borrower, I don't think that is a good way because they need to repay the loan at the right time.
We know that many people trying to borrow some money from other people but some of them having difficulties in paying the loan.
If you can make loans that have a good set of collateral behind it, you're going to mitigate a ton of the risk that comes with loans. Especially if you can physically take that collateral provided and keep it in your possession until the loan is paid back. Even if they default on the loan, you have something that you own which you can sell to recover the loss, or maybe make a small profit if the collateral is valued enough. Loans can be very profitable, you just need to know what you're doing.
Loans are also how the fiat economy grows, as a side note. Debt is literally what makes it tick. Bitcoin could run into the same situation if there was a sudden flux of outgoing loans, where there's less Bitcoin in the network than what needs to be paid back between interest and the principal.
