My reply to her is this:
It is generally not advisable to take out a loan to purchase Bitcoin or any other cryptocurrency. Cryptocurrency markets are highly volatile and the value of a particular coin can fluctuate greatly in a short period of time. This means that the value of the coin you purchase with a loan could drop, making it difficult to repay the loan. It is important to do your own research and make sure you understand the risks before investing in any financial product, including Bitcoin.
What is your advice?
I suggest not to invest when you are ready because borrowing money to buy bitcoin is a very high risk thing, what's more, the cryptocurrency market is very volatile, so avoid things like that, buy bitcoin when you are ready and accept all the risks because there is no bitcoin guarantee will go up do your own research before buying.
