1  Economy / Exchanges / Just had account hacked. Please help :S. on: March 28, 2019, 01:05:37 PM
Hello fellow bitcoiners I have recently had my account at an exchange compromised and am out to the tune of tens of thousands. Harsh day to be sure. I realize there is little hope of ever seeing that money again but I would like to investigate this as far as I can. I have the bitcoin address the funds have moved to as well as several IP addresses that were used to carry out the attack. If anyone thinks they can help please message me.

I have changed relevant account information and contacted the exchange. Any suggestions of next steps would be appreciated.
2  Bitcoin / Mining support / Safe Temperature for s7's on: October 22, 2017, 06:52:12 PM
Hello everyone I have recently started running an antminer S7 and was wondering what temperatures are considered "safe". Not looking to break my new equipment! I put my miner is what is usually the coldest room in the house, and it has now become the hottest room in the house(I am hoping that by running this through the winter I can lower my "effective" cost of electricity by reducing the need to keep my electric heat on all winter.).

Anyway my questions is what should I be aiming for with regards to the internal temperature. I have the frequency and fan settings at default. right now my temperature reads: 60 66 61. Is this alright? Do I need to perhaps open a windows or buy a fan / ac unit?

This has also given me an idea of using miners as space heaters in living areas. My chief concern here is noise as it will be in the same room where I relax and watch TV. Any one have any ideas here? Profitability isn't as big a concern here as any electricity it uses would have been used anyway by a regular heater. I'm thinking maybe just underclocking some units and then lowering the fan speed, but I would love to hear everyone's thoughts on this as well!
3  Bitcoin / Mining support / Power supply for s7 on: September 22, 2017, 09:57:43 AM
Hey guys, I recently purchased a used s7 off ebay and it came with 2 power supplies. The issue i am having is that each power supply only has 8 pci connectors.

Is it a bad idea to only attach 2 connectors to each hash board? It seemes to boot up but I'm hesitant to run it like rhis..

What id like to know is 1. Is this at all risky? 2. Does this reduce the efficiency of my miner? If any of these are yes, what do you guys suggest as a power supply? The official bitmain one, or something else?
4  Bitcoin / Bitcoin Discussion / Random thoughts on the recent and upcoming hardforks. on: August 18, 2017, 08:23:23 PM
The aftermath of the BTC/BCH split means that the market is less afraid of hard forks.

On the day of the hardfork I facetiously asked on reddit:

what is the limit then? Why don't we do a fork every day? Fuck it, lets continuously compound the shit outta this, and all go buy Maserati's
I meant that as a reductio ad absurdum but if the upcoming 2x split has a similar positive(ish) outcome, we may see the flood gates open as everyone with a half-baked idea on how to improve the network comes out with their own hard-fork.

This raises the question about the so called 21mm hard cap on the number of bitcoins. If the chain can simply be copied to infinity, doesn't that compromise the inflation-resistant properties that made bitcoin so popular amoung people concerned about the inflationary nature of the current financial system?

I do not believe so, space on each particular network will still be limited, and tokens belonging to those networks will thus be valued. But which network will be valued? And who gets to claim the bitcoin 'title'.

People mostly are looking at hash rates and price differences between BTC and BCH and probably plan to do the same thing during the hardfork in November.

These metrics are interesting and important but may I propose another way of measuring who gets the crown; the chain that spawns the most new valuable hardforks. If I esiewert, decided to create a new hardfork years down the road, I would have to choose which chain to split from. I could bcash, bseg or bseg2x. By then the ownership on each chain could be radically different. I will choose whichever one I feel has the most support behind it and / or would be most responsive to whatever changes I propose. Eventually the market will decide on a particular chain as the 'base' from which other forks happen. Speculators will pile into this everytime a fork occurs that has any value, and this chain will have massive value.

Unless I am mistaken the upcoming fork will be from the BTC / core / segwit / bitcoin chain.

HODL on gentlemen, HODL on.
5  Economy / Trading Discussion / Kraken API help on: June 09, 2017, 12:44:03 AM
I have never made a program that interacts with a website's API before but I am trying my hand at a trading bot! I am writing in python and so far have it so that I can query the public data just fine.

example:

import requests
import json
from pprint import pprint

pairData = requests.post("https://api.kraken.com/0/public/AssetPairs", data = {})
pairDataJson = json.loads(pairData.content)
pprint(pairDataJson)

But I can't seem to wrap my head around the private methods (the whole api-key / api-sign / nonce stuff). I understand I get my api-key by logging in through the website, but from there I am stuck.

Can anyone give an example of what a post request would look like for the private methods?
6  Economy / Service Discussion / Cryptsy open orders not executing on: July 18, 2014, 02:09:10 PM
I have recently been trying my hand at trading alt coins via cryptsy, all was going well untill last sunday. I had an open LTC position and placed a sell order for 0.01469 btc/ltc and then went to a hockey game. When i came home insaw that the price had risen above .0147 yet my order went unfilled and i am infact still left holding the LTC. I took a screenshot of my order and of the chart that clearly shows the time stamp on my oder is before the candle that includes the price rise to .0147.  I am at work now but can post the screenshot later this evening.

I submitted a ticket to cryptsy but have not gotten a response back yet. I was wondering if anyone has had this happen before and if so what the outcome was, did cryptsy do anything to rectify the situation ?

I would like to commit larger amounts of btc to my trading activity as i had bern profitable up to this point, but i am wary of doing so if i cant rely on my orders executing!
7  Economy / Securities / VTX on havelock crashing! on: November 28, 2013, 01:37:07 AM
So as a shareholder in the Canadian exchange I can't help but notice I've lost ~ 75% of my invested bitcoins over the past month with shares now trading for 0.1 BTC.  I was curious if anyone here has any insights about the things affecting this company and its stock.  Logically I would think that the stock price measured in bitcoins should be positively correlated to both the volume in bitcoins traded on the exchange and to the price of bitcoins, yet even though these two things have trended up over the past month the share price has tanked. Any theories as to why?

I do believe that the shares were the target of a pump and dump scheme several months ago, so perhaps that destroyed investor confidence? Another factor could simply be the lack of information about how the company is doing makes it hard to value.

So lets do a quick back of the napkin calculation shall we? volume over the past 7 days has averaged 5133 btc  5133 x 52 = 266916.  The exchange charges 1.5% both ways so 3% per txn. 266916 x 0.03 = 8007.48.  8001.48 x $1000 = $8,007,480 gives us a (very) rough estimate for revenue. at 0.1 btc per share and 10,000 shares outstanding (representing 10% ownership of the company) the market cap for the company is 0.1 x 10,000 x 10 x $1000 = $10,000,000

Now the big mystery is what kind of profit margins is the company enjoying?  Lets throw in 10% for an estimate (for a comparison microsoft is 28% intel is 21% and facebook is 21%)

this gives us earnings of $800,148 which makes the price to earning ration = P/E = 10,000,000/800,148 = 12.49

for a comparison facebook = 97.18 microsoft = 14.02 intel = 12.89 Mcdonalds = 17.53

Basically this stock is trading at multiples as though it were a blue chip company in a mature industry, for gods sake it has a lower P/E then McDonalds!

Given that this should probably be viewed as a small cap growth company I would say that there is alot of room for multiple expansion and I am hoping we are near a bottom!

Full disclosure: I increased my position in this stock by 50% today.

8  Economy / Service Discussion / where to buy small quantities of BTC cheapest in canada? on: August 24, 2013, 09:30:32 PM
I am just wondering if anyone can tell me what the best service is for buying small quantities of BTC (around $20 - $50) for the smallest fee?  I like to purchase small amounts of BTC frequently to cost average my position, and to make buying them a habit.  With the fee changes to CaVirtex it costs me about 12-26% of my money in fees when I do it like this, so I was hoping someone could suggest another service that isn't so expensive for me.
