I support your decision, OP, if you don't take risks, there can be no success, success requires trade-offs. Many people said you were too risky but now you are profitable, that proves them wrong. If it were me, I would also borrow money to invest because I believe in bitcoin and believe in my abilities.
It's too risky to have to borrow from other people to invest even if it's in Bitcoin, because if you believe in your own abilities, you should also know the limits of your ability to invest. Not even borrowing to make investments, because that will really burden you beyond your own ability. So invest wisely and also in accordance with your own abilities, not by forcing your will by taking a loan, because the intended risk is on our own capital, not on taking a loan to make an investment.
Taking risks is necessary for success, but it is also necessary to be aware of the dangers involved and make informed judgments. While it is true that success necessitates trade-offs, it is also critical to weigh the risks and rewards before making any financial decisions. Believing in oneself and the success of one's investment blindly might result in big losses.
Maybe he also doesn't fully understand the level of risk that he should know and sort according to his needs. The point of taking risks for success is to have the courage to make a move based on a decision after making research first, not to dare to take a loan for an investment. I still think it's ridiculous if someone who wants to invest has to make a loan first, because for me that's not courage in taking risks, but recklessness in taking risks.
