I just bought into R23 based on the high recs you guys have and some personal recs that were made to me...
I just looked at the stats and ran some calculations and I am worried I may have made a mistake with this one. Please don't take this the wrong way.. I am not trying to flame anyone here; I should have asked these questions before buying and I take full responsibility if my $$ are lost. But I know dz has a great rep so I was really surprised when I ran numbers (yes, *after* I purchased I know this was ass-backwards). I am just trying to understand if I made a bad investment - and to learn from it if so. If my assumptions or calculations are wrong (I hope they are), please tell me!
From the stats page .. it looks like R23 is earning only about 0.1152 BTC per day gross and has earned even less - a total of .5772 - during the past 7 days to date (Jan 22-28). At that rate, R23 will have only about .9228 gross BTC at the end of the month in 3 days.
1) Will there be a payout on Feb 1? I hope not, because is there is it appears that hosting (and to a much lesser extent management fees) will consume about 50% of the revenue (or will this be pro-rated for the partial month)?
2) .1152 BTC per day seems really low for 540 Gh/s of hashing power. I have a 150 Gh/s (partially defective) btmine hasher and 2 180 Gh/s antminer s1's that I just put up yesterday and they earned almost .19 BTC in the past 24 hours - they have about the same hashing power as this GB (550 - 560 Gh/s) (running a mix of Eligius, 50btc, Ghash and Slush's pools). Also, the statistical (long run average) return should be closer to .248 BTC per day, according to the calculators. Are there any reasons why is the per diem return is seemingly so low on the R23 miners, and should we expect that this will represent future performance?
3) I am concerned about the hosting fee .. at $700 per month, it appears that there will not be any profit at all in R23 even with the best assumption of per diem earnings (.248 per day). I ran the calculator out for 90 days (so there would be exactly $2,100 of hosting fees, assuming pro-ration for partial months) and it looks like the entire profit margin of the R23 will be eaten up by the hosting fees! And that is assuming the much higher statistical rate of .248 BTC/day under the current difficulty .. if we are only getting .1152 its going to be loss of over $1,000 (for the entire round). Worse, after only two more difficulty increases the revenue from these machines probably won't be enough to pay hosting fees and I assume the round is shut down then and our capital is lost (which would be the end of February I think).
FWIW, the calculator I use is the webified version of Zodiac1233's calculator (
http://bitcoindetailedcalculator.appspot.com/) taking the entire round at once. Output from this app follows my Q4 below.
4) If my numbers are correct, this round seems to only make sense if there were a LOT more hashing power for the same hosting fee.. I just don't see how 540 Gh/s is going to cut it with $700 a month in hosting fees at least at these difficulty levels. Is there any way to add to this round (more Gh/s) without increasing hosting fees substantially?
