what is investment, this is a placement of Capital with the expectations of making profit, well therr in no way trading is this right, I mean you're not just placing or depositing your capital for growth over time right, I mean, while trading, you're either buying or selling, wagering buyers against sellers, screaming, let the best team win 😂😂.
Definition always come up with another meaning to what some persons believe something to be, just like how you see trading as a non kind of investment thing while the definition you just render says that since profit comes at the end is considered as an investment and in trading profits and loss do normally come to some persons who have spent all their time on it, so if the definition had mentioned that anything that can give profits and also take it back is not an investment then trading would have been off from it, actually I'm only trying to make a comprehensive knowledge about your definition and non or in relation with trading.
