The fall in prices can indeed create emotional burdens for fear of losing, and even though it is difficult, we must be able to think positively that the market will be able to recover.
Only one thing leads to frustration - expectations. When they do not correspond to what is happening in reality, we are usually upset.
Therefore, it is important not to have expectations that may not come true. It is better not to have any expectations at all, then you can always be surprised and rejoice at what is happening.
It depends on the willings of the holder. Someone looking to make a profit in a short term basis will always be frustrated, while real holders are already adopted with crashes. It's not really about mental health rather than a normal fear of non experienced users. If someone doesn't take volatility under his considerations, then better to invest in fiat or stable coins and keep using banks.
