I'm still thinking about whether to buy bitcoin. you understand that now is a difficult time and you can not risk your last money.
You need first to manage risk if you are talking about investing in Bitcoin and you should always know how Bitcoin will work and how the word volatile being applies there. Always bear this in your mind that only spend money to invest in what you can afford. Not your whole savings or a monthly family budget. Because investing in Bitcoin is not for short term purposes.
Back to OP, that is a very risky decision. Have your own money to invest in Bitcoin. A lender is very risky, why not to keep your won coin in your wallet.
