You do not have to search for how Binance makes a profit from their market because I am sure Binance will not tell you. That is their secret and what we only need is how we can make a profit. If you lose in trading, just consider that it is a donation for Binance because you use their services and I am sure you can make more profit in the next trade. We want to see Binance still become the biggest crypto exchange, but do not forget that new exchanges can launch every month and every exchange out there will have its potential to become bigger like Binance.

I don't think you understand how Binance which is a crypto exchange works exactly. When you buy or short some coin, you are not buying or selling from Binanace. Binance is only the exchange. You are buying and selling with other customers like yourself thru Binance. They are not trading against you, you are trading against the other customers.

The way you make or lose money is if somebody else is making or losing money. Its zero sum except for the fees which is what binance gets with every trade. For everytrade there is a buyer and a seller. Its an open market. There are some markets which can be very illiquid which might not even have a single bidder, because it means no other traders wants to take that position because they won't make money off it.

I think it was from their own pocket Binance is a big company and they already have many services offer they are making money on trading fees, coins and token listing, mining fees, and other services.

So even with the market crash, I think they could still afford and pay those who win on the futures trading.
