Trading is like gambling as well, taking risk without assurance in gaining profit when you invest BUT compared to gambling its way safer to put your money since its not associated with luck only. You must have knowledge and skills to prevent yourself from investing in shitcoins or failed project.

Both has risk but gambling is more on luck unless you're into sports betting wherein you need to have a knowledge in the particular game that you want to place your bet.

Well they might have similarities but if you think about the way how to deal with both, you'll realize their differences and its up to you of what you think is more profitable when you engage yourself.
