Why would someone who's just starting out on their bitcoin investment want to start with a loan in the first place, something you are not familiar with and you want to start with borrowed money is the definition of someone making a financial mistake
I wonder why one will chose to do such,
First of all Bitcoin investment is made with discretionary income not even your money, so going as far as borrowing money is just ignorance. Even if Bitcoin has 100% guarantee the positive results will be realised after years, before then the interest of the borrowed money is already close to the profits you have realised in Bitcoin so it is not worth it
There are situations where a person can take a loan to invest in bitcoin and it wouldn't cause any problems as long as they are not planning on paying back the loan from the profits they will get from their bitcoin investment, success isn't guaranteed but if that was not even the case it is still a long term investment so the loan will have to be paid for from an alternate source which is your discretionary income.
My point is that a newbie shouldn't be considering this as an option to buy bitcoin with, they are still too new in the bitcoin investment space, they've probably never experienced any DIP yet and without knowing how they will react to it, after using a loan to buy bitcoin they might not be able to keep themselves from selling too early.
I agree that borrowing money to invest in Bitcoin changes the nature of the investment. Once you're under pressure to repay a loan, your decisions are often driven by deadlines rather than conviction. That's when emotions like panic start taking over, especially during market volatility.
I would only add that saying invest only what you can afford to lose is a good advice, but for long-term Bitcoin holders, it's also worth thinking in terms of what you can afford to leave untouched for a long period. If you need the money in a few months, even a good investment can become a bad experience because you may be forced to sell at the wrong time.
Bitcoin has historically rewarded patience, but no one can guarantee future returns.
