I think that whale only can "suck" you if you donīt study and learn how to trade, markets and movements.
The problem of many people is that they think theyīre investors or traders just with take profit with a coin or an operation and donīt dedicate time to study how to work. And when they lose money. "The whales are guilty".
i am little bit agreed with you because i am working on bitcoin from 2015 when its price was 230$ but then whales were not in bitcoin. i know very well about bitcoin and i know how to trade i am not in the loss but i am awarding peoples after that they know how to do them in this case. my opinion is that buy on the dip and sell on top don't wait for the moon its should be dangerous
