- Jun 18–28, 2017 – 11,548.52848689 ANC: Diversifying endowment
fund, converted to 64.67993426 ZCash. This fairly small transaction took 11
days and we needed to use 2 accounts with the BTC38 exchange to hurry along
this process. The tiny Chinese BTC38 exchange can only process small amounts
per day and has a lot of hidden traps which slow down transactions. For
example, we quickly learned that Bitcoin withdrawals didn't work well at
all, it seemed the larger they were the more likely they wouldn't happen
at all. 0.05 BTC and 0.1 BTC withdrawals took over a day.
A 0.25 BTC withdrawal took 2 days. A 0.5219 BTC withdrawal never worked
(was refunded). Problem was that they were paying too low BTC transaction fees.
We worked around this by turning BTC to CNY (Chinese currency) to Dash as
an investigation showed that Dash had lower transaction fees than Bitcoin.
(Bitcoin is currently suffering from high transaction fees.)
Later on as we learned more we turned ANC directly to CNY and then to Dash.
Reviewing the latest exchange logs, it seems that everyone at BTC38 is
following our lead on this, and ANC/BTC trading has dropped to nearly zero.
After the 11 day ordeal was over, we converted the Dash to ZCash in one quick
transaction at Bitfinex. We used the BTC38 exchange as it was pretty much our
only option for selling off ANC (Anoncoin).

Expenses covered by nonbitcoin donations:
- Apr 1, 2011 – $1,874.40: HP Pavilion Elite HPE-570t with
2GB DDR3 ATI Radeon HD 5570 was used for all mining. The primary goal
of this machine was for other Lifeboat functions so none of its price
will be charged to our Bitcoin Endowment Fund. (This otherwise monster
machine had a fairly small graphics card.)
- Mar 29, 2013 – $299.99: Gigabyte AMD Radeon HD 7950 3GB GDDR5
DVI-I/HDMI/2x
Mini-Displayport PCI-Express Graphic Card
(Eventually returned for a replacement because we couldn't get it to
work.)
- Apr 2, 2013 – $151.79: Computer Guy (Attempted to get Gigabyte
card to work plus emergency replacement of power supply.)
- Apr 2, 2013 – $0.00: Gigabyte AMD Radeon HD 7950 3GB GDDR5
DVI-I/HDMI/2x
Mini-Displayport PCI-Express Graphic Card
(Eventually returned for a refund of the $299.99 price of the
first card ordered because we couldn't get it to work
and we then gave up on this brand.)
- Apr 3, 2013 – $25.90: 2 of StarTech.com PCIEXSPLIT6 6-Inch
PCI Express Power Splitter Cable; 1 of StarTech.com 6-Inch LP4 to 6 Pin
PCI Express Video Card Power Cable Adapter; 1 of StarTech PCI Express 6
pin to 8 pin Power Adapter Cable
- Apr 3, 2013 – $8.15: 1 of StarTech.com 6-Inch
LP4 to 8 Pin PCI Express Video Card Power Cable Adapter
- Apr 8, 2013 – $314.40: Sapphire Radeon HD 7950 3GB DDR5 HDMI
/ DVI-I / Dual Mini DP with Boost PCI-Express Graphics Card (And it
worked on the first try!)
- Apr 8, 2013 – $199.99: VisionTek Radeon 7850 2GB DDR5 PCI
Express Graphics Card (Ended up being useful in debugging oclvanitygen
bugs.)
- Apr 8, 2013 – $5.45: 1 of StarTech 6in 4 Pin to 8 Pin EPS
Power Adapter with LP4 - F/M
- Apr 8, 2013 – $89.99: Corsair CX750 Builder Series ATX 80 PLUS
Bronze Certified Power Supply (You really want a monster supply like
this to run a HD 7950 card because of the high amperage needs of such a
card. The HD 7950 uses at most 150 watts but needs about
25 amperage on its 12 volt rail.)
- Apr 13, 2013 – $149.99: Corsair Professional Series AX 750
Watt ATX/EPS Modular 80 PLUS Gold (Modular setup meant no unnecessary
cables and therefore better airflow in the mini-sized tower that was
being
used. This is also a more efficient model than the last power supply so
it generates less excess heat. The other Corsair is now a backup
power supply. And none of the
various adapter cables are now being used but are stored for future
scenarios.)
- Jul 31, 2013 – $419.99:
EVGA GeForce GTX770 SuperClocked with EVGA ACX Cooler 2GB GDDR5
256bit was ordered so we could switch from AMD to NVIDIA to work
around
oclvanitygen bugs that cause high-end AMD cards to run at one quarter
their potential speed. Unfortunately this card was incompatible
with our
HP Pavilion Elite HPE-570t so we returned it and ordered an ASUS
graphics card since the HP had a Pegatron motherboard and Pegatron was
part of ASUS at the time that the HP was manufactured.
- Aug 16, 2013 – $409.99
ASUS GTX770-DC2OC-2GD5 GeForce GTX770 2GB GDDR5 256-bit, DVI-I/DVI-D/
HDMI/DP PCI-Express 3.0 SLI ready Graphic Card OC-selected 1110MHz core.
This card was also incompatible with our HP Pavilion Elite HPE-570t so
we worked to get a low-end computer to handle it since it was looking
pretty hopeless to get a GTX770 running in the HP.
- Aug 30, 2013 – $120.00 for a Dell GX620. This computer only
had room for a 1-slot graphics card so it was returned. (This was
bought from a local dealer.)
- Aug 31, 2013 – $250.00 for a HP xw400 workstation. (If
you are wondering how we could find a workstation for only $250, the
answer is that the workstation which was originally priced at $3,400 is
a bit old.) This was
bought from the same dealer that provided the Dell GX620. This
workstation can handle up to a 5-slot graphics card (such a card doesn't
yet exist) and handled the ASUS card fine. Note that EVGA has better
techsupport than ASUS and their card seemed a bit sturdier (bigger
heat sink) as well but
it wasn't worth it to return the ASUS card to get the EVGA card back.
There is always a possibility that the HP xw400 workstation would be
incompatible with the EVGA card…
It is worth noting that a bunch of adapter cables that were bought
previously are now being used with the HP xw400 workstation as its power
supply only had one 6-pin PCI-E power cable, and the EVGA card needs one
6-pin and one 8-pin PCI-E power cable. Amazingly, testing so far shows
that the power supply in this old computer is powerful enough to handle
the ASUS card after the adapter cables were attached to it. If it
wasn't
powerful enough then we would have used our Corsair CX750 power supply
which was purchased earlier.
- Sep 2, 2013 – $25.89 for an ARCTIC F9 PWM Case Fan and a
Noctua NF-B9 PWM Cooling Fan. The HP xw400 workstation rear chassis
fan was making a noise like a jet engine when the case cover was off as
for some reason oclvanitygen was using not only 100% of the GPU but 100%
of the CPU as well. (Maybe the dual core CPU is easily strained?) The
case cover was off because we
were using an
external power supply during testing. Amazingly the noise problem went
away when we eventually put the case cover back on. Perhaps the thick
metal that this workstation is made of is especially good at blocking
noise? The CPU is still under 100% load. Anyway, the testing is still
ongoing at this time so a final determination has not been made.
- Sep 20, 2013 – $0.00 – We fixed oclvanitygen so it now
runs almost four times as fast on our Gigabyte AMD Radeon HD 7950 3GB
GDDR. You can
download our free fix.
Learn how we created the only version of oclvanitygen in the world
that runs under Windows and runs high-end AMD cards at full speed!
(At the time of this writing we have already generated 3 1Lifeboat
addresses on our ancient HP xw400 workstation with its high-end NVIDIA
card in a few weeks while generating 0 1Lifeboat addresses on our HP
Pavilion Elite
HPE-570t which has been using a high-end AMD card for over five months.)
- Sep 27, 2013 – $97.47 for an
IP Power 9258T Network AC Power Controller. Our
HP xw400 workstation is crashing about once a day for some reason so our
solution is to monitor it with a ping and then to reboot it automatically with
the 9258T when it doesn't respond to a ping. Turning off overclocking on the
graphics card didn't solve the problem and the machine does pass a thorough
memory test.
- Nov 17, 2014 – The fans on the Sapphire Radeon HD 7950 are failing and
it turns out that Sapphire's warranty service is quite poor. (They only handle
warranty service via email and we have received no response yet from the email
address even though it has been a few days. In addition, the web reports
poor service from
their warranty service.) We have now ordered a replacement Sapphire Radeon HD
7790 7950 7870 39mm 85mm Video Card Dual-X Fan for $19.77 from eBay.
- Nov 29, 2014 – We got some response from the Sapphire warranty service
so we spent $8.85 at Office Depot to ship the card back. Installing the
replacement fans would have voided the warranty so we will save them for
further use in case we have later problems with the card fans.
