Altcoin margin trading refers to Altcoins trading with leverage. Leverage trading, in general also known as margin trading, is based on the following principle: The margin trading platform allows the trader to open larger positions than his equity would allow. The amount of leverage determines how much the trader’s position can be greater than his equity. The trading platform lends the rest to the trader. This loan is usually subject to fees that are higher than normal trading fees. Furthermore, the trader is liable for his position with his stake (margin). If the price goes against him, the trader loses a part or even up to his complete altcoin stake, if he doesn’t save his position in time with a stop loss.
