Advantage of big capital. With huge capital, you can become a millionaire overnight if you trade right, with well skilled knowledge, but also you can become very rekt too.
I also don't agree on this part. Even how big or small your capital is, it will still depends on how you will trade, like the risk management or the risk:reward ratio.
Even your capital is small, your profits will be few so your loss will be only few. So if your capital is big, huge loss comes with huge profits also.
That's why even your capital is small, if you are a well and good trader, you can make that capital to generate a profits.
