1  Economy / Currency exchange / Looking for a reputable firm to act as agent on: January 15, 2018, 10:16:44 PM
I am looking for a reputable firm to act as a buying agent for my company. The idea is that you will invoice my company for a purchase of Bitcoin. The motivation is so that I can use www.plastiq.com to pay your firm (via domestic wire) for services and goods rendered.

Ballpark $100k. I will accept currency fluctuation risk with proof of your purchase at a pre-arranged time. Willing to pay a small consideration, give me your offer and situation. Helps a lot if I know you or you have standing on the forum.

Also appreciate any info about who would be interested.

Cheers.
2  Economy / Securities / Looking to buy PUT options on ASICMiner on: June 07, 2013, 10:12:52 PM
Hi there,

I'm trying to figure out a way to buy PUT options on ASICMiner stock, or, less ideally, short sell it.

Ideally, I'm looking for options with an expiration of a few months and a strike in the range of 1.5 - 2.0BTC.

Is there any way to achieve this, or am I SOL? The options listed for sale on btct and bitfunder don't fit the criteria, and I'm looking to buy, so I can't write my own.

Update:

I will immediately purchase ASICMiner puts expiring September 1st, with a strike of 1.8BTC, and a premium of 0.14BTC.

3 BTC limit.
3  Bitcoin / Mining support / Orange sparks shooting out of rig on: May 24, 2013, 10:23:40 AM
Uh... On one of my rigs running 3x 6950s, there were orange sparks flying out of my case at a slow pace, one every couple seconds. They were very visible in the dark, I don't think I was seeing things. The rig was still hashing and everything. I switched it off immediately at the PSU.

All 3 cards are on unpowered 16x-16x PCIe risers.

What steps should I take before turning it back on?
4  Alternate cryptocurrencies / Altcoin Discussion / [YAC] Illustrated, step-by-step guide to starting your own AWS YAC server farm! on: May 11, 2013, 08:04:14 AM
Hey there! Just as the title says. Keep in mind there are other, faster ways to go about this - this guide is geared toward being accessible rather than efficient.

Before we begin, two very important things:

1) YOU are responsible for making sure this is a profitable venture. Don't spend money you can't afford to lose. If it's too good to be true, it probably is. Etc etc etc.

2) This guide involves executing a bash script that I wrote to set up the instances in one easy step. DO NOT EXECUTE THIS FILE WITHOUT MAKING SURE IT'S SAFE WITH A TEXT FILE EDITOR FIRST (nano, vim, etc). You don't know what kind of nasty things I could have put in there, and you can never be too safe.


Ok, let's get started!

First, go to Amazon Web Services (http://aws.amazon.com), open an account, and set up a payment method. If you can't figure this out, you probably shouldn't be running servers  Wink

Once that's done, go to the AWS Management Console. You should see this:



Click the EC2 link. You'll see something like this, although you may be in a different region and you won't have key pairs/placement groups/security groups yet:



Now, click Spot Requests on the left sidebar, and click the "request spot instances" button. Select Ubuntu 12.04.1 LTS for Cluster Instances (Ubuntu for servers should work fine also).



I'm going to do this demo with a cc2.8xlarge instance, which has 88 ECU (a measure of computing power) and makes about 750kh/s. You should do your own cost analysis and choose the cheapest type of instance. You may also want to get more than one instance.



One of the most important fields here is the maximum dollars you are willing to pay per hour. I entered 0.35. Again, do your own analysis. Keep in mind - if the market rate exceeds this amount, your instance will be terminated and any YAC you haven't withdrawn from the wallet on your server will go along with it. Click continue. If you're launching more than one server, make sure to create a placement group on the next page. Otherwise, just click continue again. Click continue on the Storage Device Configuration page.

The Key Pair page is important. You want your servers to be secure - create a new keypair, give it a name, and download it somewhere you won't lose it. Click continue.



This next step requires you to know your local IP. Type "my IP" into Google. Make it look like the image below (make sure you select SSH), then click "add rule" and click continue.



There will be a confirmation screen. Make sure everything is correct, then click continue.

You should now see a screen like this (without the terminated instances, of course):



Wait until the instance is confirmed (circle turns from yellow to green). You will have to click the refresh arrow a few times, and it might take a couple minutes. Then go to the Instances page (link in the left bar). You'll see the following:



Wait for "initializing" to disappear under "status checks" and be replaced by "2/2 checks passed". Then, right click the instance, and click "connect". You'll get a dialog like the one below. Follow the instructions - an SSH session will appear. It will tell you it can't verify authenticity - type "yes" and press enter. You will not need to do this the next time you connect.



You should see this once you're logged in:



Enter the following lines of code into the console.

Code:
wget https://downloads.sourceforge.net/project/vycid/setupunix.sh?r=&ts=1368081732&use_mirror=master

You'll see this:



It may appear that you didn't get the prompt back. Don't worry, just enter the next line in.

Code:
chmod +x setupunix.sh?r=

You'll see this:



Just one more step between you and mining! Enter the following, then sit on your hands and wait for your terminal to look like the image below. DO NOT CLOSE THE SSH SESSION!

Code:
./setupunix.sh?r=



Okay, you're off! The server will download the blockchain (it's short, won't take too long), then start mining. Here's 3 commands you'll need:

Code:
./yacoind getbalance
- gets the balance of your miner account

Code:
./yacoind sendtoaddress <address> <amount>
- use this often to get the YAC out of your server's wallet. Remember this is a spot instance, so it can be closed at any time if the market rate goes above your maximum rate, and you'll lose any YAC currently in the wallet. You can write a script to empty it periodically, but I can't help you with that.

Make sure the amount you send is at least 0.01 YAC less than the getbalance amount to allow for the transaction fee.

Keep in mind the blockchain has to be downloaded before any blocks can be found. This won't take long, since it's still quite short. You can check the estimated hashrate with
Code:
./yacoind gethashespersec




If this guide helped you, maybe kick some of the YAC you mine over to me at Y2JcwhZu9m6cqPZ3Jv8iKspcJYNY5wa5zc   Wink
