I did exactly that when it dipped below 20k (sentiment was very bad). Wouldn't do it at the current price though. I didn't put up collateral and the monthly servicing payment is low compared to my pay. The loan was also not that big in absolute terms. If those conditions are not met, I wouldn't do it. I just wanted to take advantage of the low prices and pulled forward some future buys.

Today I would just buy at every paycheck.. I'm still doing that as well.
