Does anybody know why nobody are making this anymore ?

I mean there is a demand for mining gear at all levels. Not all miners buy mining gear for profit.
I used to deal in ASIC USB stick and this bitcoin price jump created lots of inquiries about my now extinct merchandises.

I mean if ASIC USB stick which is defo not profitable can sell, you could sell any miner heck bitmain even made a router that mines and is now sold out.

So why is there nobody making pcie based card ?I mean demand is not only profit driven. Some people mine just for the heck of it, some people want to learn about mining process at a low cost i.e university student doing research or a wannabe miner,  some people feel the need to support the network and so solo mine ... who knows he/she hit a jackpot and win 12,5 btc.

I guess it's about technicality or just not profitable to manufacture any ideas ?
