As i know there are 2 type of trading, that is margin trading and spot trading, all asset like crypto, stocks, commodities and forex we can trade it by spot and margin trading. Spot trading will be have lower risk than margin trading although we can make profit only from up trend, and margin trading have higher risk because of high leverage. In margin trading more possible our balance going to zero from wrong prediction but in spot trading especially on stock and forex market is our balance not to be going to zero because this asset has low volatility.
