For the long term, I think trading is the most profitable since what you need is skill in trading and the skill you acquire is not limited only to cryptos but in all types of markets.
exactly we cannot actually over emphasize the values of trading if you have a good skills in other to invest at the right time. Investment is a game of skills and if you can train yourself in other to be able to spot opportunities then sky will be your limits on what you can make. Mining is good but now I have realized that trading is far more profitable compared to mining.
