I don't see where the idea comes from that increased mining hashrate increases a coins' price.
A higher gold price causes increased interest in gold mining, not vice versa.
I believe the thinking is:
faster hash rate = more coins = more profitability -> drives more miners -> more interest => more speculation on the coin
There are some iffy transistions but that seems to be the 'pump dump' / penny-crypto way
Currently there are some farms specifically mining DNR masternodes to hodl. Taking a guess here, but people using FPGA's might not be dumping which could over time increase price since they might be more hashrate than the smaller miners constantly dumping. Obviously excited to hear about public FPGA's in general.
If these turn out to be real I wouldn't mind being able to bump up the devfee as a huge thanks for doing this.
