Maybe iam missing somethink, but i dot understand current situations about FPGAs, a lot of firms selling them but most of them doesnt show performance.

And few of them reveal some info about super profitability on some "non existing" coins..

Advantage of FPGAs should be a lot of usable alghorhitms, whitch makes them better than asics..

And now, there is preorder... maybe idlike to preorder, but how, when i dont know what is possible to earn with it
