Investing is profitable during the bull market only but trading is profitable everytime even during the bear market because a good trader can short to gain profits. Most of traders are bad because they can't predict bull-bear reversal and get rekt or transform to investors.
both have the risk. You can get an investment profit when the price is pumping, but if it decreases, you will get a loss. as well as trading. it's just the difference is the time. Personally, I chose investment, because I feel that trading is too risky for now.
