Personally, I wouldn’t leave my job to trade in crypto, especially if I am new to the market.
It's not really advisable for someone who's new to the market to leave their jobs. Why leave your job if you can do both of it at the same time? The market is open 24/7 and you can always learn and do it after your job.
Borrowing money to trade in cryptocurrencies is also not a wise move. The market can’t be trusted. You could be in debt. Whether you trade in crypto or any other market, have a steady source of income to support you and invest. Otherwise, it can take a bad toll on your health and financial state.
This is a big NO choice. You don't borrow money to put it at risk, you're just getting more risk of what you do. The risk of paying only the interest and not the whole principal amount if you dwell in losses.
