You know binance is a strong and the biggest exchange in the bitcoin transaction kind of life, but i have not seen them offering loan or they have specific customer's they issued loan. I want to know the criteria or the qualifications of getting in this exchange you made mention of
On Binance, you can open a margin trading account, or open a future trading account. In margin trading account, you can borrow up to 10x of the amount you use as collateral. In future trading account, you can borrow up to 50x to 125x of the amount you use as collateral, even up to 200x or more on some exchanges. You can use it to trade and that is what the OP is talking about, but he only use margin trading in respect to thread. The more the amount borrowed, the more the risks of losing.
before someone gives you a loan you must be well known and a pattern to the platform, now they informing you to issue loan, their is a very big secret behind, i believe the advantage they will take from you will be more beneficial than the loan giving to you. Just know the kind of form or documents you put online.
The advantage is that you can use high amount to trade. The disadvantage is that it is more risky and liquidation price will be closer and if reach, the collateral used will be liquidated. The exchange, like Binance used as an example will make more profits in trading fee because the person borrow money and have more to trade with while the exchange deduct fee in percentage of the total amount used to trade.
