A lot of whales are also waiting to buy in cheap, they are stepping on each others toes to get in the door. When bitcoin hits 3k levels there is simply too much buying pressure. You can be too greedy by not selling but it can also backfire by waiting for cheap prices that may never be hit again, always cost average your buys.
You are right mate people are happy to buy bitcoin and waiting for the opportunity to buy at very low price of 3k dollar. Whales use to plan and sell high amount of coin to make the market down. For this purpose they use new users and make them sell panic but in actual fallen price is to buy more and store for long.
