Anyone will be tempted when they see that the price of bitcoin can reach the ATH, it could be said that the profit is already in hand and missing this moment is of course something that is difficult to avoid, when the price passes the ATH, which has happened of course the selling pressure is very large, making it difficult for the price to rise higher.
To reach the previous ATH it will take strong support from the investor and most of the time btc breaks its previous ATH with little effort. The sentiment became so bulish and the market created such FOMO that the market got more buyers than sellers. However most of those who bought btc at its previous ATH already sold their holdings or liquidated them through future contract or lowered their average buy through DCA. So i don't think this will be a problem to be concerned about.
