The blueprints are NOT what makes long time players hard to beat in industry. Just buy researched copies. What makes expert indu players good is their knowledge and infrastructure. The magic is in the buyback programs, jump freighter alts, knowing the market cycles and spreadsheets. And for T2 production no researched blueprints are needed anyway. ME and TE do not carry over when inventing.
Someone nice donated me a couple of good selling fully researched blueprint originals. Turned out it wasn’t such a gracious thing than I thought because to get that 10%-15% return on investment those BPOs can generate a huge amount of 0,1ISKing buyorders, hauling to a system with a good production index, hauling stuff back and 0,1ISKing sellorders was needed. That was in highsec.
Nullsec turned out to be totally different. Materials and ore come from alliance buyback, tons of BPCs from BPOs researched a loooong time ago where on stockpile and a 10-20% markup to Jita prices are fine.
