That may be true because even how good a trader you are, there will really be a time where you earn almost nothing. Trading is quite the risk since you are trading with a very risky digital currencies because of its market price volatility. You may bought a crypto at a very low price today and only realized that it will pump after a couple of years.
Lol. The last statement really got me laughing, but with the way the cryptocurrency market is presently, the level of FOMO and new traders, it is always very easy for us to see those who would prefer to join a moving train, hence in a couple of months for long term holding, you may be in profit.
I feel you though, and the thing is that we cannot know what to expect from any market and sometimes even TA can still fail us, but in the long run, it is better than just predicting and expecting only luck (which is the real gambling) to take its course as trading requires skills to get the best of it.
Everything generally about life is gambling since we cannot predict the next outcome and we are only trying our best to get it right. For instance, a
surgeon performing an operation even though a good one, may not know what the outcome would be for the patient after the operation, lawyers may not know whether he or she will end up winning a case and so on with other professions, but at the end, we always hope that with our skills, we can at least get it right most of the time.
