Can't be helped. The whole altcoin industry is largely abandoned by speculators and long time investors. The herd will go to where the herd will go. During these times, you will know which developers stuck around even when the financial gain is actually negative.

How exactly are those idiots wrong this time and were not wrong last time? When BTC gets back at ATH, all those non-idiot rational "investors" will be back FOMOing empty promises on white papers because they are unable to make a difference between turd and gem. Next time is not going to be any different, it will probably happen much quicker and percentage-wise not as much, but it will happen no matter how deep in denial you are.
