I always had hard time convincing myself to buy Bitcoin with a loan from bank. Eventually I bought some around 20-21k levels with something like 1k usd loan with 0.5% interest. It definitely doesn't kill me because I work so I have fixed income. But as I explained, if rates are not good enough and you are not having good income its best to not buy Bitcoin with a loan. I wish you best with your purchase. I guess you (OP) already made profit as price is higher now. Also its best to put that Bitcoin into earn program so you can generate more for future.
