The futility is to put in on the public market and expect to make a profit when other people are actually competing.
If you want to build things that help, you can join several groups (without leaving your corp)
eg
or RvB that I often see fighting.
Just so you know, I often actually keep the stuff I bought for profit and actually use them to craft, to give to people, or just giveaway.
Though I also often just reprocess them, like when I have 3B of stuff I bought and I just can’t sort out. reprocess ALL the stuff !
