Small funds will certainly take a long time to generate a lot of profit, but if you are consistent it will also increase. Collecting funds by borrowing from a bank is a solution that will be risky, because there will be a return on the loan along with the interest that is the new dependent. Do not take a loan if you do not have a definite and consistent income. It will plunge you into even greater debt.
Somehow I agree with you, AakZaki. There is a burden that borrowers have to bear when they borrow money to trade or invest in crypto assets. Highly not recommended for anyone who does not have the ability and skill in trading, but even they will not be guaranteed to be able to repay the loan smoothly without problems.
Volatility is the most common reason why people shouldn't loan for trading, but if they have collateral, then I think it's safe for them to get a loan. In the long term certain assets will generate profits, but it is also not guaranteed when the time will come.
