It's similar to taking loans when the price is down and there are many people who do that. While it's not the worst idea in the world, there are a few problems like what would happen if you need to pay the interest and the economy/price goes further down. Also there are times when the expected return is less than that of the due interest and that causes a lot of problems.
According to me, loans must be taken taking into consideration the profits you are going to make with it. Just because there is inflation doesn't sound like a great reason for taking loans. If you have done the calculation and your income will be higher than the interest, then go ahead and take the loan!
Creditors will take into account all the points that will relate to their profits, you can be sure of this. The moment of high inflation will most likely be spelled out in the paragraph on force majeure, and in this case an additional indexation on interest paid for the use of money can be applied. A loan is always higher risks, especially if they are taken for high-risk investments in cryptocurrency.
