I will agree that it is kind of ironic how many of us do have a tendency to gravitate towards nice round numbers including yours truly....

There is another aspect about having goals that is nice, too, even if they might not be achieve, it is good to have targets, and frequently we can even surprise ourselves regarding how a previously seemingly "unachievable" target comes within reach.

Frequent posters here repeat ourselves, but I would like to repeatedly admit that have a bit of an abstract goal to NOT allow my BTC stash to go below a certain admittedly round number, but in the end, similar to you, it remains a kind of random goal that I would be more than willing to violate under certain currently unknown opportunistic circumstances.
