My experience shows that both Forex and Crypto trading are risky but can be filtered as the two classes are associated with their varied degree of risk. By Forex, I combine all traditional assets including Gold, that's the general way of viewing this in the traditional offering. If it's currency trading, it's too risky but the major pair are still better. However, despite the huge volatility, I prefer Gold, Index and Stock trading in this category.

As for cryptocurrency, the risk of each asset is associated with volatility and liquidity. The more the liquidity, the less manipulation you would witness, so I've seen the trading of Bitcoin and Ethereum as better reasonable in crypto trading.

Now, in both categories, I further choose Gold and Bitcoin, while Gold earns me more money with higher risk, Bitcoin earns me money with lesser risk.
