Aside from what everyone has said, i would also advise to only invest what you can afford to lose.
Yes, this is a very basic matter in crypto investment. We must use the money that we can afford to lose. Sometimes, there are people who use all their money in crypto investment because they are influenced by the story of successful people in crypto. This shouldn't happen because it may lead to severe losses. Well, I really agree with your suggestion, sir.

I think I also will advice newbies to not using loan money. I see some of my friends using loan money to buy crypto coins. Even if they use the money to buy Bitcoin, I think it is still too risky. For the safe investment, I believe it is not good to use loan money because it must have the deadline for repayment and loan interest, too. This can lead us to hurry selling the assets.
