I'm sure not all traders will agree with me but some could possibly be on my side...
Here are the reasons why;
1. It is quite stressful - old traders will soon give up due to mental health problems
2. It is not enjoyable anymore - nobody will stay long in a job that they no longer find themselves comfortable with especially if you are not earning well.
Most of the time we feel this during bear season.
3. Trust issue due to Scam growth - traders never find it safe to use exchanges, even big exchanges.
Oh, bro, I am glad you naturally have reservations about what you alleged. As for me, I am surprised about what you wrote concerning trading because most of them are particularly not true. Fine, trading is risky but today, there are a few who could tell you categorically that they do nothing for a living other than trading. In that sense, what is that if not their job? This is simple and practical. I know a few of them that are traceable trading alone and they are very living fine. Not only that, they are living large and some are adding other businesses to it to be impactful in life other than trading alone. The internet should be able to tell you a few as well, and if not for my side hurtling now that can't make me say it with all confidence, I should be a testifier to this as well by now in my little way. I have survived with trading for almost a decade, there are challenges though especially if you are from a developing country, but overall, I am very sure that trading is a job for some people, but a risky one for that matter. That's the issue.
However, below are my quick responses to your numbered claims;
1. Trading is not stressful and you have your choices. You may be a short-term trader in which day trader is inclusive, a medium-term or long-term trader. With the latter two, you will not even know you are doing anything. However, retirement is certain at a point if you want and it is not peculiar to trading or a certain age.
2. Trading is ever enjoyable to those who know it very well and earn from it. But if you are such that has it otherwise, then it is not for you and it is never by force. "Trading is not for everybody."
3. This is why you partner with the right company. It is never an issue as well.
