Taking out a loan to invest in bitcoin is extremely risky because the cryptocurrency is unregulated and volatile. Bitcoin is a long-term investment, and the price can rise and fall at any time. How will you pay back the loan? It is preferable that you have a source of income so that if prices fall, you will not feel the pain.
Loans are only more suitable for use in more real trades, for example, such as opening a business buying and selling daily necessities that are always selling every day. Not to be used for investment because it will indeed be difficult for a borrower in terms of paying it off when it is due, unless the person taking the loan does have other income every month which income can be used to pay off the loan.
But still, it is highly not recommended because considering the risks are not small, so I say that loans in the form of money are only suitable for more real trading capital because the money can be rotated regularly so that it is not so difficult for the borrower to pay.
Right, taking a loan is very risky, we still remember that sometimes bitcoin took up to 4 years to pass the last ATH, and since bitcoin dropped from $ 69k to below $ 20k a lot of news said that many were stressed because they sold assets and prices bitcoin until now has not been able to pass ATH in 2021.
After a price decline, of course it always takes time for Bitcoin to increase again and it is indeed a very natural thing for Bitcoin when until now it has not been able to pass ATH in 2021 because ATH is indeed difficult to create every year so you and everyone need to be patient if would like to see ATH again in Bitcoin. So give Bitcoin time to reach its ATH again in the coming year and I don't think it will happen in this year either.
