Thats very interesting question. Who knows?
Bitcoin is unpredictable. Price today is undervalued. But it was overvalued. Taking a loan in bitcoins can be very risky if you cannot pay it back. You risk to lose your goods. It might be good for loan taker to take when bitcoin is high price and to return it when it gets low. Or to buy when it is low and to keep it when it gets back up so return then and looks more human like.
