1  Alternate cryptocurrencies / Speculation (Altcoins) / How to calculate Ethbull arbitrage? on: February 03, 2020, 01:49:30 PM
I have a question about how to figure out the correct pricing for Ethbull which is a 3x leveraged erc20 token.

The description for it reads that it is designed to move 3% for every 1% ethereum moves. I'm looking at the charts for it on tradingview and having a hard time understanding why it moves the way it does.

My question is: How do you determine what the correct price for ethbull should be and how do you take advantage of arbitrage when it is not correctly priced?

For instance, looking at a recent swing on eth shows these prices:

======== ethbull   ethusd
17-Dec   464   122.96
3-Feb   1364   188
Ratio    2.94     1.53

In other words from dec 17 to today ethbull increased about 3x and ethusd increased 1.5x. That would mean ethbull moved 2x what eth did, not 3x.

Why is it like that? What is the formula to take a chart of ethusd and plot what the correct price for ethbull should have been?
2  Bitcoin / Mining speculation / Extracting profit from mining heat as thick slab wood kiln on: May 30, 2019, 01:16:15 PM
I saw this mentioned a few times in other threads but nothing with very much detail so I thought I'd make a thread to see if anyone had done something similar.

The basic idea is to use the excess heat from a mining farm to dry thicker slabs of wood than what you can normally get at wood supply shops. Thicker slabs are more valuable to wood turners and things like bowl blanks can sell for quite a bit of money on sites like etsy and ebay.

There is an infinite amount of free wood on craigslist. Tree service companies will often happily give away the trunks they remove because they have to pay to have it hauled off.

Light bulb kiln for Drying Wood: (update) woodturning with Sam Angelo

Has anyone done something similar to pipe mining heat into a wood kiln in such a way that the wood dries within a month or so without cracking?
3  Alternate cryptocurrencies / Altcoin Discussion / Sites that list whether new ICOs are using Ethereum vs Neo vs other platforms? on: February 04, 2018, 11:07:13 AM
Is there any easy way to get a list of what underlying smart contract platform various new ICOs are using?

There are a lot of sites that list upcoming ICOs but I can't find any that also have an easy way to tell what those new coins are using as their platform.

Ultimately I'd like to scrape the data and have a way to generate a spreadsheet that shows whether platforms like Neo are starting to win out over Ethereum or if Ethereum is just dominating everything else.

Is there any relatively simple way to do that?

4  Alternate cryptocurrencies / Mining (Altcoins) / Best way to duplicate bootable USB drives? on: December 30, 2017, 05:09:41 AM
I've been using Win32DiskImager to make img files of NVOC USB sticks and Etcher to make duplicate sticks.

I often get sticks that don't work at all, they boot into Linux then get stuck with a "BusyBox" message and iniramfs prompt.

Should I be using different programs to do that or is there a special setting I need to get it to work?
5  Alternate cryptocurrencies / Mining (Altcoins) / How to set NVIDIA GPU core speed from ubuntu command line? on: December 27, 2017, 10:59:16 PM
I have a 1070TI and I am looking to set:

gpu clock=+200

I am able to do that using simpleminer. How can I do that using the nvidia command line programs?

Here is what I have so far:
sudo nvidia-xconfig -a --cool-bits=31 --allow-empty-initial-configuration
sudo nvidia-smi -pm 1

sudo nvidia-settings -a [gpu:0]/GPUPowerMizerMode=1

sudo nvidia-settings -a [gpu:0]/GPUMemoryTransferRateOffset[2]=700
sudo nvidia-settings -a [gpu:0]/GPUMemoryTransferRateOffset[3]=700

sudo nvidia-settings -a [gpu:0]/GPUGraphicsClockOffset[2]=200
sudo nvidia-settings -a [gpu:0]/GPUGraphicsClockOffset[3]=200

When I check the result, I am able to change GPUMemoryTransferRateOffset but not GPUGraphicsClockOffset:

    nvidia-smi -i 0 -q

        Power Readings
            Power Management            : Supported
            Power Draw                  : 123.36 W
            Power Limit                 : 125.00 W
            Default Power Limit         : 180.00 W
            Enforced Power Limit        : 125.00 W
            Min Power Limit             : 90.00 W
            Max Power Limit             : 217.00 W
            Graphics                    : 1733 MHz
            SM                          : 1733 MHz
            Memory                      : 3802 MHz
            Video                       : 1556 MHz

I am pretty sure the thing I need to change is "Clocks... Graphics... 1733 MHz"

I believe "nvidia-settings -a [gpu:0]/GPUGraphicsClockOffset[2]=200" should be affecting that value but it is not. Does someone know what I'm doing wrong?
6  Alternate cryptocurrencies / Altcoin Discussion / Making a rig resetter using something like arduino or ethernet home automation? on: December 22, 2017, 02:10:34 AM
I don't have the hardware skills to make such a thing but it seems like it should be simple for someone with the right background to make an arduino (or something similar) that can connect to the internet and allow you to have it complete a circuit on your motherboard's reset or power switch to power cycle a mining rig.

The normal rig resetters are out of stock ATM and it's surprising there doesn't really seem to be anything else to fill the gap.

Is this something someone has already figured out but I was not able to find it?
7  Alternate cryptocurrencies / Mining (Altcoins) / PSU Burnt Up The End Of A Cable, Throw It In Trash? (Pics Inside) on: October 23, 2017, 02:03:23 AM
I plugged my GTX 1080ti into my seasonic 750 watt PSU like I had done several times before for mining. Upon starting the machine it caused the fans on the GPU to spin very fast. I shut it down and found that it was very difficult to remove the cable from the PSU. I eventually got it out and found that the ends of the cable were burnt apart. Here are some pics of the burnt end and one of the OK end which was in the GPU:

Should I toss the PSU in the trash? Is there any way to see if it's safe to use perhaps for a lower watt machine that only uses around 250 watts?
8  Alternate cryptocurrencies / Mining (Altcoins) / How to get mobo to see more than 2 GPUs on: October 17, 2017, 02:14:46 PM
I am migrating a working GPU/PSU setup that I had on a windows 7/ Intel i5 computer. On my new system I can only get it to use two gpus.

The BIOS setup screen will come up one any of two GPUs I have in the motherboard but the third gives a blank screen. I have tried swapping the order of the GPUS, they are all working fine but the motherboard only sees two.

I've tried it with riser cards and mounting them directly to the motherboard. All the GPUs are powered correctly from two PSUs. I have also tried with with a 3rd PCIE video card that doesn't need power and it gives a blank BIOS screen when it's GPU number 3 but it works fine when it's the only one on the mobo.

Is there something I need to do in the BIOS such as enabling additional PCIE lanes?

I'm using:

Motherboard: GIGABYTE X299 UD4
CPU: Intel Core i7-7820X
PSUs: 2 x 750 W
GPUs: 3 x 1080ti

Thanks for any ideas you can offer
9  Bitcoin / Mining support / Exhausting heat into house cold water line on: August 27, 2017, 02:24:06 AM
I'm sure someone must already be doing this but I've looked around and can't find anything.

Suppose you did something like this:

Basically you have a heat exchanger such as from a car's heater core inserted in your house water line after the shutoff valve. Whenever someone uses any water in the house it will draw new cool water through the exchanger.

This will slightly heat up both the hot and cold sides of the faucets but unless you have a giant farm it will probably not be that noticeable on the cold side.

Has anyone done something similar? Would a car's heater core be able to hold the PSI needed or is there something else that is actually designed for doing this type of thing?

I'm getting a lot of "Share above target" messages when I put cgminer in verbose mode. My hardward ghs as reported in cgminer is right, but in the pools it always gives me a lot less credit, like half. Here's a log:

Here are some ways I've tried invoking it:

rem causes "Share is above target" messages
rem cgminer -o stratum+tcp:// -u me.1 -p 1 --bflsc-overheat 90

rem also causes "Share is above target" messages
rem cgminer -o -u me.1 -p 1 --bflsc-overheat 90

rem also causes "Share is above target" messages
rem cgminer -o stratum+tcp:// -u me.worker1 -p 1 --bflsc-overheat 90

rem also causes "Share is above target" messages
rem cgminer -o -u me.1 -p 1 --bflsc-overheat 90 --fix-protocol

Any ideas on what this is about or how to fix it?
11  Other / Beginners & Help / BFL Bitforce miner getting slower and slower, from 20Ghs to 3 on: November 13, 2013, 06:20:29 PM
I just got what was supposed to be a 25 ghs BFL Bitforce miner in the mail. When I 1st started it up it ran at 20 ghs. Then it started running at around 7 or 8, now it's at like 3 or 4. I've only had it on a few hours.

What's going on? How do I fix it?
