That 3m is what you'd have to sell it for to break even.
Noone wants to break even, we all want profit, which is why the profit for selling it at 5m or 10m was listed.

Keep in mind the costs get insanely higher when you do crystals

Here's how that simulation came out:
400

Phase	High	Mid	Low	Cost
Appraisal	3	97	300	40,000,000
Upgrading Lows	3	123	1	19,500,000
Upgrading Mids	14	0	1	12,000,000
Total				71,500,000
Break Even Fee				5,107,143
5m Profit				(1,500,000)
10m Profit				68,500,000

4000

Phase	High	Mid	Low	Cost
Appraisal	47	1091	2862	400,000,000
Upgrading Lows	47	1345	3	171,900,000
Upgrading Mids	157	8	3	173,500,000
Total				745,400,000
Break Even Fee				4,747,771
5m Profit				39,600,000
10m Profit				824,600,000

High grade crystals are going to be quite expensive because 5m doesn't even meet their break even fee for low volumes.

And ofc none of this takes into account inflating ore/crystal prices. Costs will dramatically increase when you don't have the ores to begin with and have to buy them.
