The whole crypto space is littered with 'buy the dip' and the primary counsel before that advice seems to be fading away but without that primary advice, you might cease to exist in the space,
even though surely guys are going to want to have had boughten on the dip - even if the BTC price might keep dipping they might run out of money or have to resort to holding because they have run out of money (or maybe just buying when their paychecks come in and not really over doing how much they are buying) so that they might still be able to have some money even if the BTC price keeps dipping in order that they might be able to buy some more BTC at lower prices.
Some may want to buy on the dip, even if the BTC price continues to decline, they might run out of money or need to hold off until they have more funds. This strategy allows them to have some funds available even if BTC prices keep dipping, enabling them to purchase more BTC at lower prices.
