Taking a loan to buy btc at 18yo

I’m fresh out of high school as a carpenter. I make good money and work a lot if overtime. I have zero financial responsibilities, I’m not going to collage and I want to stack up debt to buy btc. Im currently dca 3300$ into btc every month but i would rather just pay that in interest or you know a good debt. But the problem is I’m from Scandinavia and in my country they are very strict on loans and I’m pretty sure I can’t even get one until I’m 21 or have enough assets. Is there a safe place where I can get capital on an exchange or something where I can stack up btc?
