I think that is a very big NO and very bad idea if you wanted to invest in cryptocurrency keep in mind that you should invest what you can afford to lose knowing that there is a high risk when dealing with cryptos.
It is a short no.
Someone who invests in crypto and using not his own money, he's just making himself into trouble. Investing in crypto is profitable but it takes time and is a wise choice.
Not every borrower has that wise choice so they're likely to end up in debt and losses.
