Greed and fear of losing is the engine of the market! And those who can not control their emotions will always lose! Manipulators specifically now create a situation in order to force people to sell at a loss.
I completely agree - emotions and crypto (or investments in general) don't go well together. Patience is the key.
I've noticed that after coin/token enters an exchange, price drops soon after. As I see it, there are 2 options to get as much out as possible: 1) sell as soon as possible after crypto is listed (and buy back in a couple of days after price inevitably falls) or 2) hodl long term and wait for the price to get more stable.
