Trading without a source of income is very hard, because trading needs a capital, and if you don't have a source of income you will sure fall down into loan and you will having a hard time to pay the interest of the loan, and when the crypto market down you will surely become disappointed.
It's okay to take a loan if you have a source of income, but if you don't have a source of income, it's not okay, simple logic, right? So if you do trading activities, you must have money
to buy crypto assets, you can't have none.
But if you participate in airdrops or bounties, even if you don't spend money, you can still trade, but you still need funds for the transaction fee you will make.
For me I think if one has a source of income their is no need taking loan to trade. With a source of income you can actually trade with the amount you can afford comfortably but taking loan to trade while one has a source of income it means one is not trading with the amount that he can afford, taking loan us just like a back up.
The reason why I don't really encourage loan in trading is because trading is unpredicted. I feel taking a loan and if the outcome of trading is bad it means the lose is not just only in the trading outcome but also to the loan that was taken and that must be paid back .
