Trading is better than investing. Because what you do is buy and sell. This field requires experience in a market before entering. Therefore, for a beginner like you, you should focus on investing a little amount first and practice trading. Experimenting is the bestway to learn. Or watch videos about trading. Hope this will help you decide!
Actually, it depends on the ability and willingness of each person. So I always recommend learning first about the basics of cryptocurrency and the ways to get it. Understand all the risks that may occur. Thus you will find the best way.
Trading and investment have their own risks. In general, it would be ideal if doubling funds owned through trading, then profit is used for investment.
