But the question is what if you do not own enough money for investing? can you take a loan and invest?
Only what is advisable is to borrow money for business. Some people can take the risk and borrow to invest in bitcoin, if they study the market very well, they can be lucky, but, yet, not a good advice.
Because if you look deeply into charts of inflation rates in most the countries you can easily understand taking loans even with high interests could be useful and profitable.
Especially, this would be a good idea in developing and underdeveloped countries where high inflation persists (but fiat is inflationary generally), but not a good idea. It would rather have been better using loan for business.
Personally, I don't suggest doing this because using other people's money will put me under stress and this can have negative effects on my decisions. What do you think?
Yes, not good at all, what if the investment plan go wrongly, that will be a big problem for the person.
Have you heard about
die borrow die strategy before. You can read about it.
About the borrow aspect of it, rich people prefer not to sell their asset because of the high tax, because of this, they borrow in which the tax would be reduced if compared to selling of property or asset. Let me use bitcoin being an asset as an example. If I have certain worth of bitcoin, but because if I sell it, much money would be paid to the government in tax if compared to borrowing of fiat, I will rather borrow. First, because fiat is inflationary. Second, because tax that would be paid in borrowing fiat will be reduced if compared to sellimg of bitcoin holding directly. Because of this, if someone borrow, it is not a bad idea at all.
