Trading is more like gambling. When you sell, if the price goes up, you lose and if the price goes down you win. Personally, i tried trading and it is very risky. I would constantly sweat as i watched the prices go up, and would check charts every single minute i was free. For trading, i would recommend you at least have some knowledge in reading charts otherwise you would not go very far. Trading also requires a lot of time and patience, in the sense that you can't panic buy or sell when you see the price moving. Don't try trading if you can't bear to lose a few dollars in the short term.

On the other hand, investment is the safe bet. Just leave the funds there for a week/month/year and let the price grow. I think this is the best option as it leaves you with time to work or do other stuff. You can also pick coins that provide DIVs such as VEN, COSS or Kucoin Shares.

Either method is fine, and both have it's benefits. As i have stated above, trading provides short term benefits, but is also more risky and more time consuming. Investing is the slower and safer option, leaving you with time to do other activities. Take your pick, they are both pretty good since you are involved in cryptocurrency.
