In general, trading any financial instrument can be dangerous. Especially one that's new to you.
All financial instruments have different character of movement. Therefore, before you start trading on real account, carefully study movement of asset on the chart. I also recommend you to open several orders on demo account.

It's all about volatility and leverage size. Depending on volatility, broker set a certain amount of leverage for this group of assets.

It is safe to trade soft commodities if you take into account what I have written.
