Hi,
can someone point me in the correct direction to get info like block reward, expected hash needed for mining one block based on current difficulty (average), and other metrics needed to calculate mining dash metrics ?
thank you
The one from bitinfocharts is wrong. Coinwarz has it correct. You can always check the difficulty directly on the blockchain of dash (explorer.dash.org)
In december nobody known what the difficulty will be, but presumably you'll roi in a few months at max. The high increase is because the D3...
There won't be a significant technology update until 7nm asics are available, some time in 2019. TSMC's 7nm is still in early risky production and at it's not available for the asic market.
There might be a revised version of D3 (say D3+) somtime next year but it won't make a huge difference...
