I get the point you are driving at an all the point you raised here makes sense, but I feels like their are few more that should be added that is not here , and the one I can remember now is that if you are investing in Bitcoin, it's very important that you invest with an amount you can afford to lose, so that if things doesn't goes as planned, you wouldn't be contemplating suicide, this is why it's very important to invest only with your discretionary income, because your discretionary income is the money left after all your basic needs have been met.
So for you to be in control of yourself if your investment in Bitcoin doesn't play out as expected, you must invest only what you can let go, because in as much as the potential of Bitcoin is very bright and huge, nothing is guaranteed in the future, so invest with caution.
One must also understand that investing in bitcoin with a borrowed fund is a dead trap in disguise because it's an investment that requires servicing for better returns .
You can make all the researches but not when investing with a borrowed fund.
You can be patient but not when you are investing with a borrowed fund.
No, I disagree with you here, investing with a borrowed money is not a wrong decision entirely if it's done in a calculated manner. You can invest with a borrowed money if the repayment plan is done installmentally, and it's spread across three years or more, and another thing is that you should kill that notion that you will be paying back from your Bitcoin investment.
Since it's a loan that can be payed installmentally, you can easily be repaying bit by bit from your paycheck at the end of the month, so before you know it, you will be done repaying it, and to buttress it all, if you took the loan and buys during a dip and the interest rate is as low as 0.6% a year, tell me why it's not a good idea? Because I know that Bitcoin will always outperform that interest rate attached to the loan, so it's not a bad idea entirely, but if these are not the condition for the loan, like repaying installmentally and it's spread across 3 years or more with an interest rate from 0.7% below, it should be avoided, because it's a trap as you called it.
