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.
This is the tendency to happen when you do wait up too much or patiently waiting for the bottom price which isn't still discoverable.Yet we know that Crypto is indeed a very unpredictable market.
Regarding on my buying behavior I do always buy up when I do see its already the bottom.If it did dip even more then buying out again.Its risky but the tendency of percentage loss would lessen
unless if you have bought all in on a certain one point than making gradual buy orders.
