>>2141973Generally because when people fish with bait they tend to stay in one spot and chill while waiting for a strike. Hence the term "soaking bait".
Lure fishing on the other hand tends to be a more active form of fishing (casting in/around a particular spot for a few mins then moving on) than soaking bait since most of the time you don't have that nice live/dead bait smell on your lure that would normally attract them to you.
