If the profitability went from $500 a day to $40/day shortly after the first batch got plugged in, surely once the second batch goes live its not a huge stretch to go from $40/day to $1/day. Don't think its worth it for batch 2, within a day of receiving it it will be worthless...and that without even mentioning Obelisk...
Not quite how that works. Pretty much nobody earned $500/day, those were on paper numbers. I got mine early enough that I think I got $100 on the first day, but it was down to $50 day two.
Adding more to the network isn't the same as debuting on the network, ASICs blow GPUs out of the water, they change the dynamic of the network. Adding more just dilutes it a bit, but the initial launch exponentially drowned GPUs out.
