Whenever I trade and make a profit, does someone else lose?
For example, I've been watching an altcoin market for three years and knew that a certain currency always triples in value going from x to 3x in a couple of months. Having spare money avaliable I put some in to test the strategy and I'm close to my 3x at the moment.
My question is, whenever I trade and make a profit is there always going to be someone who's made a loss or is this an odd way of thinking? Could it be that these people are losing a small amount of money or that these people are buying a coin by going (I'll put 10% in that) so as to not really matter if it profits or. Loses as it generated a stable ish value.
Not necessarily that someone must loose because you made profit from your trading. They will only lose if and only if they sell their holding below the market value they bought the coins in question.
