OP, where do you believe would be your mental state today after seeing the sort of price movement Bitcoin has been doing?
¯\_(ツ)_/¯
You'll be paying interest + the principal for your loan, paying for funding for your margin traders, AND your ROI is NOT 100% assured. You're literally "gambling" with that loan.
Taking loan from Bank is a tough call and it's risk increases further if you are opting it for Bitcoin investment. We don't know what Bitcoin price will be in coming days and week, we can only speculate about Bitcoin future price. OP has posted the question of taking loan for Bitcoin investment back on Dec 24, 2024 and price on that day was around 98k. Today Bitcoin price has gone down to 83k and we don't know when price of Bitcoin will go up above 90k or it will go further down from here.
My advice is a big NO to OP and all other who are planning to take loan for Bitcoin investment.
