I would say don't quit.
Markets rise and fall daily, you always have to sell for whats best for you. If its not a price anyone is willing to pay then you will learn, that's a big part of the game. If it does sell, then you know that it was worth that much to at least 1 person.
If you are unable to sell your bp, you should collect the resources needed to click it, I am willing (and I am sure many others would) to click it for you free of charge just for the fun of helping out(and the discovery)
Then you would have the plates, and know what their stats are and have an end product you can sell to people or use yourself.
Good luck man and congrats on the discovery
