Trading , since mining is also profitable but we need to keep in mind very well with the perfect descion whether we should go with which particular coin mining and also we need to find out that whether your electricity costs is very high or low then your mined coins from.your miners and also you need to keep in your mind that the climate where you are living is better or not that remain in favour of the cryptocurrency mining hardware .
Here my recommendation for you is that don't always think that trading will not Result into profit because , trading is the principle way of making earnings in cryptourrency market , so better to do work in trading also with mining .
Both of them are risky but if you will keep patience then surely with time you will make profit .
