I've tried it but I don't feel like I have much benefit from that method. Unless we really have quite large capital. Because sometimes the price difference between Cex is not that big. Or sometimes it returns to the same price quickly. But this method is still possible. But it must be an altcoin that has fast transaction speeds. Because if we do this on an altcoin that has a very slow network confirmation speed then we will be late when sending it to another exchange. But for now I don't use that method. Because it's too risky. Because sometimes we experience losses when prices decline and we actually lose in transaction fees.
