I agree but a person with a stable financial situation shouldn't borrow to invest in an unstable asset because the risk involves means that they may now go into debt if the market crashes. But I know that there are people who like to take risk and are ready to deal with whatever comes.
Honestly taking such risks seems like a decisions at an odd hour, there would be no results. Having a good records file can enable you take a loan but at that point it isn't a good idea, I know this is what most big companies do, they tend to give out loans to their debts free staff but alot times they find it hard to pay back and have themselves in debt. Though taking such loan to buy BTC is a good choice but the aftermath should be considered as well.
