Both have risks and they need some knowledge. Investment has a wide variety whether it is business, land, property, or stock. Trading on the other hand is more about stocks, crypto, or forex. The advantage of this is that you can do it at home which is accessible unlike investing in some physical things where you'll need to be there to check it.
Having both is good because it means diversifying your investment and if both are successful then you'll be earning a profit. Just choose what risk you take and be good at it rather than not risking at all.
There are risks in every business but our aim is not only to make profit but also to keep the risks in mind. In business where we do not have knowledge and experience, the risk of loss increases. A good experience and knowledge can improve our profit rate. Of course there are many methods and types of investments.So before investing in any business one needs to learn.
There are some businesses that you cannot control from home and you have to physically go and check these things yourself, but crypto currency is an investment that can be done from the comfort of your own home. Both trading and investing are good but I think investing is relatively easy whereas trading requires you to be mentally engaged all the time. The risk of loss is less in investing than in trading. Trading is a difficult task, and only a well-experienced trader can do it, so people who do not have experience and knowledge should prefer investing over trading.
