Anyway, you might want to understand that there are fees that you need to pay every time you trade. Although many platforms don't charge a fee for the maker, there's almost always one for the taker. Not to mention that fees may vary from one trading pair to another. I've never used MEXC and I don't know how their fees work but you need to check it.
Also, since it appears you're fond of scalping, don't do it with only a cent of spread. If you do that, perhaps you need to have millions to make a decent profit out of it. Otherwise, instead of profit, you will have a loss since your negligible profit might not even be enough to pay the fees however low they may be.
If your order is only worth $712 and you're trying to make the most of the difference between $57,695.00 and $57,694.99, you might want to stop it. It's not worth your time, effort, screen exposure, and so on. You'd earn a world bigger if you decide to flip burger or deliver pizza instead.
Not to mention that exchanges have this penchant to not allow you to trade your coins down to the last Satoshi. There's almost always a little amount left. In your case, this might be enough to erase what little profit you imagine out of the spread.
