Every trader wish bitcoin to have the highest possible value to gain their highest possible income. It is not being selfish but just being wise. Besides, whatever happens, the price shall not and never depend on us so why still bother to mind the reason why we are after the price is because that is exactly what we aim, to gain high income.
You didn't get it obviously. Its selfish to never be satisfied with bitcoin price and to always wish for higher price, even when price already raised a lot in short period of time. I think you didn't understand what is trader and what is investor, gaining high profit its ok but so you think its ok to wish double the money in just one day, and after you for your profit you wish more, like op said its 19.000$ but that isn't enough, people want 20.000$, but even that wasn't enough, how much profit is enough for some people?
If you can be satisfied with some profit you can earn from daily fluctuations, that is trading. Learn some terms in bitcoin before you make some statements.
