There's a lot of frustrated traders right now because they are doing their trades wrong at the first place, FOMO is not good many is losing money because of this. Now that we've seen another big pump and big dump, hopefully that those frustrated traders will take this seriously and don't think for the easy money in trading. Don't buy at the peak and sold at the bottom, this is a bad way of burning your money, don't FOMO and control your emotion all the time.
I don't know many people who ended their trading career with gains.
They don't want to be exposed for sure because you might ask for some money, and I can say that many succeed on their tradings and they just want to remain private and focus on their earnings instead of posting it online.
