If they do does that mean that mining the same thing everyone else is mining, albeit more efficiently, will become more profitable or will the network difficulty adjust and everyone will quickly find themselves back in the same rut they were in before they went down the path of FPGAs?
To have the most reward with mining (and in most things in life) following the herd is not the way. You must do heavy research and dig deep to find the gems that no one else is looking at or have discovered yet.
The world and nature doesn't work in such away that the herd gets rich. Only those willing to go the other way, maybe more risky, but lessons learned, and ability to mitigate risk with proper risk management will usually prove to be much more rewarding than shuffling along with the crowd.
btc bitcoin ethereum can be mined with FPGAs already, just gotta load up the bitstream folks? nowhere to get them? I do... know where to find me? I bet you can guess.. it's somewhere private... maybe cough cough.. my discord server!... ;)
