Discipline are additional factors in terms of making success with trading unlike with gambling if you already lose your pick there's nothing left for you, in trading if you are in a usual setup even the value of your asset fall with good discipline to be patience waiting the next market run you may able to recover and if your study serves well possible still that you'll be compensated when the market turned back and start to pump.
Well this depends on the type of trading that you're doing because if it's leverage trading that you're doing, you lose everything when the market goes against you. It's only when you're trading spot that if the market falls against you, you can hodl and wait for the market to rebounce. Most traders are gambling and that's why we don't know the difference between what we're doing because there's a big difference between trading and gambling and for anybody that has studied the market, they'll realized that trading has to do with researching before execution of the things we have learnt but gambling is mostly we just guessing without relying on much information.
