A little more diving in on the hypotheticals:
Let’s say your target ROI is ~6 months on a $10k GRN1.
Let’s also say Innosilicon and Bitmain release miners in about the same timeframe, and the difficulty is 2x what the hashrate will be with 2500 GRN1s on the market plus today’s current difficulty. That number could be within a huge range, but let’s keep it simple and hopefully this is more towards the “worst case scenario”.
So difficulty at “694,014,386.562”, and producing about ~3.15 Grin per day. To ROI in a ~6 month timeframe Grin would need to be priced at ~$17.70 and electric at $0.1 kw/h with all other numbers staying stable.
Now, what’s the phase out schedule of C31? I read that it’s around 7 months? Is that starting in October when these are due to deliver? And doesn’t C32 phase in proportionally during the entire C31 phase, meaning the last couple months will be 80-90% less or so?
Seems like >$20 Grin will be the price necessary for these to have “reasonable” ROI.
Hopefully the $1.25 million donated to Grin Dev if all of these sell will help get it there.
