Metroid you have seen that f3 and g3 asics right? Some pics or more informations? No?

I don´t now why people say that the eth hashrate spikes unnormal, but in my opinion they rise normal. GPU´s are cheap and enough in stock, new GPU´s are faster than old one´s. So don´t make panic.

And this is also the reason why the eth devs don´t fork asic resistent, it is not necessary, because the asics are to slow at the moment to centralise the eth network.
