if OP borrowed money and invested in bitcoin at 110-115k, and compared to current price of 106k. This is not a big loss and is only temporary so there is nothing to worry about. 
Personally I would not recommend OP or anyone to borrow money to invest as I am not an expert and do not know their financial situation. But I don't see anything wrong if he has a stable job and income and can borrow money with his salary (unsecured loan).
In my opinion, whether or not to borrow will depend on each person's income and financial situation. As some have said, if he can repay that loan with his income. Why can't he borrow?
Well, Bitcoin's price is at $111,000 already so he's near the breakeven price already (depending on what price did he bought), but if he used that money (assuming that he took a loan) on leverage trading and opened at that price range that you said then he's one of the millions of traders that got liquidated that's for sure. If it's a spot trading though then it really isn't a big loss. 
Like most here, I would not recommend OP to borrow as well... FOR NOW because he can borrow when we enter the bear market AS LONG AS he has a job where he can get the payment on that income without compromising his expenses and savings. I have nothing against taking a loan and investing into Bitcoin. It's just that we should know when to do it, and the best time to do it is during the bear market, not during this bull market season. It's good that there's somebody that has the same thinking as me. 

 Many here can't understand it and will just say "Don't borrow money and invest into Bitcoin because it's too risky." Like do we know their capabilities? What if he can pay that loan in a year or 2 without sacrificing anything, do we tell to them that they should not borrow money?
I hope OP is still here and reading our posts. For you OP, don't borrow now, and instead borrow during the bear market season which can happen possibly next year. 

 Just have a little bit of patience.
