It also depends on the responsibilities someone has. I just read again about taking out a loan to buy BTC. Honestly, if it is the year 2014, someone has little to no responsibilities, no family to feed and is at a young age and not exaggerating with the loan amount, I think it could be a risk that is worth taking. I have been reading some wild posts here in regards to financing BTC investments, like selling the wife's jewelry and stuff. But if someone decided to take out a moderate loan after crunching some numbers, knowing that if it goes wrong life would still go on quite comfortable, then why not go for it? I know people who have invested so much time into understanding BTC back at the time and if they came up with a well-considered approach to build their portfolio, loan money can be a component if someone understands the implications.
I am definitely not against loans, when it comes to business or investment projects. If someone has a prosperous plan and know how to make more money out of given, than a loan could be very effective instrument. Moreover, big estates are made with the usage of someone else`s money. It is normal situation and most of the people who are willing to achieve something take that risk.
