The SMA30 and SMA60 on the 3rd chart in the OP are the moving averages for hashrate, not for price. His argument seems to be that since the 30 day hashrate moving average has dropped below the 60 day hashrate moving average, that the hashrate is falling. Which is partly true as hashrate is down marginally over the last few weeks, but we are talking in the region of a few percent as you point out, and certainly not a crash as he is suggesting.
