Trading and investing both are useful, but which one is more profitable depends on market conditions. When the market is bullish, any trade can be profitable and when it is bearish, the chances of losing in trading are high. For those who are new I would suggest investing more than trading. Investment relatively less risky than trading. Moreover, an investor does not need to know much to invest. Although taken as a long-term investment, those who keep their wealth in Bitcoin will surely make a profit.
