Taking a loan to invest in cryptocurrencies is a good idea, but we must have the ability to pay, the potential for a price increase can occur in the near future because there will be a major event that occurs every 4 years, namely halving day, of course we must have the courage to buy so make our life better.
I slightly disagree with your opinion, the crypto currency market is a very volatile market, anything can happen next moment. Here any bad news can bring the market down and good news can make the market go up.
It is true that next year is the year of Bitcoin halving, after which the price of Bitcoin usually increases, that means there is a high chance of starting a bull season, but still I am never in favor of borrowing money from a friend or bank to invest in crypto currency market. Always use capital that is your own, and always invest that money in the crypto currency market, which is more than you need. The crypto currency market continues to fluctuate and you may even lose money if you withdraw when you need, because the market may have fallen at that time.
