Just buy and hold, only whales know where the price will go.
Is it only one whale that we have in the market that they will know the price direction of bitcoin, dot forget that we dint have a single whale in the market, there are whales from different locations with different order mind set, as one whale is thinking of putting money into the market, another whale may actually be thinking of how to withdraw large amount of money, and whales also depends on FOMO also, the reason why they pump money is for the value to shoot up a little bit with the hope that many people will see it as bull run and start investing in it for their own investment to appreciate, but they are also with doubts too, as they dont know if their strategy will work or not, so it is not every whales that can determine the price of a crypto, except all those smaller cryptos.
