What I got here is a very simple answer just to compare investing and trading.
Investing is when you buy someting like bitcoin or altcoin and then let it be frozen for long term to make more profit in a long run.
While trading is when you buy an item then sell it in short amount of time even if the profit is not that big.
Investing = risking what you can afford to loss if program run away scamming you
Trading = believing yourself and putting your skill to earn some good profit with what you have in your hand.
simple as that
