This issue of taking loan to invest in Bitcoin has really been discussed several times and to me i found a fair justification and consideration in most of the discussions which implies that if the demands, terms and conditions of repaying the loan can be handle outside of our Bitcoin investment which should be first determined by our general and personal circumstances and in view of time and seasons for a proper evaluation before taking such decision, if all this has been carried and confirmed to be ok then taken a loan to invest Bitcoin shouldn't be a problem for me, because am already aware of the risk and precautions has been taken prior to time.
This is only good if you are buying Bitcoin when the price is on the floor or experienced correction since you can guarantee that the price will recover immediately to gain profit that can cover you loan interest.
However, if you are loaning money for the sake of long term investment then it’s useless to pay a loan interest while you can just slowly DCA using your salary every month knowing that you can pay your loan outside your Bitcoin investment. You are just taking unnecessary interest while you are just waiting long term for your investment to grow.
Much better to accumulate slowly using the money that you don’t have any other allocation. Loan will just give you pressure for your investment.
