Lucky to those who buy bitcoin while the price was still 3k up. Bitcoin might go up now for good, and we may not see Bitcoin again to at the 3k price forever.. Or Bitcoin might go below $2k to $3k for another consolidation.
It is not the luck as I've think of it. They just buy bitcoin that time cause they know that bitcoin will recover from the dips and headed for another bull run. They believe that will happen, that is why they never lost such opportunity as it only knock once. And they are not wrong, the price is really surprising and profiting.
