my advice is don't borrow crypto because the market has high volatility. so if you receive 1 BTC at a price of $ 5000 and then 1 month will come the price goes up to $ 10k you will experience a big loss
Then it depends on how the market is going to do so, but if you can trade what you've borrowed and make a profit on it, even the bitcoin's market price goes doubled, the currency that you have is still bitcoin then, still you can pay enough what you've borrowed. Just simple as that. But do consider that after you borrowed and made a profit, do not borrow again, just develop the currency that you have.
