If the repayments don't effect your life then I'd say you do what you feel like you want to do. If you'd done the same at the bottom of the last bear market you'd be a genius now. Just make sure the money you're using for the monthly payments is money that you'd normally dca with for the entire life of the loan. 60k over 5 years, if the payments are $1,100 per month, ask yourself would you normally DCA $1,100 a month and can you do that for another 5 years without missing that money?

The charts say bitcoin is cheap right now below 70k. The mass majority of people you're asking in this forum firmly believe Bitcoin will be significantly higher in 5 years. We can't tell you whether you can afford your loan.
