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.
Theoretically when you trade and you sell for example, someone else buys your coins in the price that you trade and you consider that this price is a high one (because you are selling).
But actually you don't know which is the price that the other trader has sold/bought so maybe a trade may be a win-win.
