Do you reckon ASIC mining hardware is shipping amongst insiders?
From Dash coin, engineers where making small batches of ASIC X11 miners, long before commercial products became available to the community in April this year!
I heard the cost of ASIC miner will be high due to the big DAG file size. So Ethereum will be ASIC resistant.
Every 4 weeks, 12THS is added too difficulty, which is starting to look like small scale ASIC Hardware production is going on unofficially (in secret).
This is what always happens with ASIC Hardware. Some engineers get together with some miners and produce private ASIC hardware.
They then pre-mine a tonne of coins, dump the coins mined with this private ASIC hardware to finance the manufacture of a commercial ASIC hardware.
I'm just posting, because some people may have been thinking of more GPU's and they would never get a ROI.
