I took out a loan to buy bitcoin. I got a $10k loan in 2013, the loan was paid off in 2015. I have taken out considerably more in profit than I invested and still have most of my bitcoins. Prior to that I had bought bitcoin when it was very cheap ($3-$5) and sold it because I needed money to buy a house, once the house purchase was completed I took out the loan to buy back in. Also, at least here in the UK it is possible to arrange credit card debt to be 0% so not every investor who uses a loan or credit card to purchase btc is naive.
