i can say not worth, and this by far. I mean between $1 - $5 earnings a day before power and a price over $5000. FPGA mining is not worth and it was never worth in my opinion, the devices are too expensive.
Meh it's not too bad, looking at the superscalar k10, at 0.1$ kwh price, you are making almost 10 USD per day profit mining alephium. You can buy it from a certain asic custom firmware salesman for 5250$(don't wanna advertise). That's a 547 day ROI which is not too good or bad, but there's only like a handful of ASICs that can match this, and we are in a market state where it can't be fully called bear or bull market (at least imo).
Idk, I was considering this as an investment which is why I opened this thread to ask if people have had negative experiences with them(failing chips, etc)
bullmarket stuff: anything crypto makes money, bought 4000$ worth of old shitcoin x10 that would be 40k, defi pools and farming cost around x4-x5 compared to mining setups at the same profit but makes things very easy.
could expand my mining hardware setup(i'm pretty maxed out for now), but money well placed in crypto can buy you more mining setups hehehe
NOT FINANCIAL ADVISE LOL!
bearmarket stuff: all those things don't make you money LOL!
