1. It is quite stressful - old traders will soon give up due to mental health problems
No job isn't stressful. It depends on how to deal with the difficulty on the job. If we can deal with it, we can enjoy it without having a pressure. As long as we don't set a minimum target to reach daily, I think trading isn't very stressful job.
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.
Sometimes, we must evaluate our trading activities. That's will help us to fix the problem in our trading. If it seems not enjoyable anymore, there should be a problem in our trading. We need to fix it soo, so we can still enjoy it. Instead of quitting trading, why don't to try fixing the problem? So we can enjoy t again.
3. Trust issue due to Scam growth - traders never find it safe to use exchanges, even big exchanges.
That's why traders never store much money into exchanges. After we do trading, we can send again everything to non-custodial wallets. Also, we must be careful to choose coins for trading. If we don't trust new coins due to scams issue, we can choose top coins. I think it is only about how we do trading in a more secure way. Choose the most secure way!
