So here’s my question
Would you take a $50K bank loan to invest in Bitcoin today?
Or is this just deja-vu waiting to go wrong?
I don't know where you are from but if you are from a 3rd world country then $50k is a lot of money, and whoever can borrow that amount of money must have assets worth many times that amount. It means you are considered to be financially well off and are looking to make a big investment.
If so, why not seek advice from financial advisors in your area? Because in my opinion, through direct communication between you and them, they will know exactly your condition and will be able to give better advice. Instead of seeking advice on social media when you haven't even provided your financial situation. How can we give you useful advice when we know nothing about you?
