Don't expect half-price H-boards or rigs to appear on the store any time soon. Tytus and I are not believers in the endless-doubling of difficulty theory promoted by sites like TGB. We'll mine our own equipment before we fire sale hardware.
The competition will soon put you out of business as a hardware seller, if it hasn't already, regardless of what happens to difficulty, unless you drop your prices alot in the next month or two.
BTW, will you ever port the improved chainminer back to v1 M-boards?
. I believe that there's the same headroom for overclocking, you're just starting from a higher hashrate.
