1  Economy / Scam Accusations / [SCAM] Crex24 sudden KYC - while Crex24 wishes to stay anonymous on: April 27, 2020, 09:48:21 AM
What happened::

In Dec 2018 I opened an account at crex24.com and was able to deposit and trade ARI and MEC. I regulary tested if I *could* withdraw, but waited until I have enough BTC to make up for the withdrawal fee.

When I recently logged in last week to put some sell orders for above Altcoins I had deposited, I couldn't place any orders or withdraw anything and was presented with a truely worrying KYC procedure asking for a wealth of personal data. I have not received any advanced information or warning from them.

Crex24 wants me/you to submit:


  • photo of current ID / driver license
  • social media profile (not mandatory, but very much recommended)
  • selfie holding ID card used + signature
  • two different utility bills, though they seem to prefer credit card and bank statements
  • complete address

I was about to bite the bullet, when it came to two different proof of residence documents, at which point I spontaneously wondered with whom I am dealing with here. So being confident that an exchange asking for so much KYC information certainly has a legal address listed on their website I started searching. Turns out they haven't, the best information you can find in their web page is

So I mailed support asking for their legal address and received the following reply:

After that I demanded that I receive my coins back without KYC which naturally was refused.

The issue is that I am suddenly asked to do KYC with a lot of personal details but crex24 itself is refusing to even display a legally valid business address of themselves.

I have registered my account in Dec 2018 and deposited coins into your exchange under totally different provisions and since I am unwilling to do KYC with an unknown party I am now requesting my balance to be sent to me and my account being closed after that, notably without doing your very much detailed KYC procedure.

The Crex24 replies did not quote my previous mails, I have edited that in for easier understanding. Though the textual content is absolutely unchanged.

Additional Notes:
Crex24 asks you for the most detailed KYC that I have ever witnessed (and I've done a few meanwhile), while not even giving you their basic information like a business address. The details of information they request and the lack of detail they are willing to reveal about themselves is deeply worrying and hints to something more sinister.

Flag:
I have also raised a flag against Crex24 and would like to ask you to consider it for supporting or opposing:

2  Alternate cryptocurrencies / Marketplace (Altcoins) / Looking for a verified gate.io user on: December 31, 2019, 10:07:39 AM
I am looking for a trusted member who is verified on gate.io.
I need to sell one of my old coins which is only traded there and do not want to verify by passport just for this one sale.

The coins are not tainted in any way and have been mined by me many moons ago. We're talking about a market value of roughly $500

If you are a verified gate.io user and trusted member here, please let me know what commission you would like to get for selling my coins there. I have somewhere around 5% after all fees in my mind but am open for negotiations.

Thanks in advance.
3  Alternate cryptocurrencies / Mining (Altcoins) / [OVERVIEW] Scrypt AUXPOW Coins on: July 14, 2019, 12:26:30 PM
Since I have always been a fan of merge mine (AuxPoW) coins, as they basically run on free hash I decided to compile a comprehensive overview of all currently active scrypt merge mineable coins. This hopefully encourages pool ops to consider one or the other coin.

Please post corrections and additions, I would like to keep the OP updated over a longer period of time and therefor need your help.

4  Economy / Services / [SERVICE] Linux/BSD System Engineer w/ +20yrs experience on: July 12, 2019, 09:08:29 AM
Hi,

Thanks for taking your time to read this.

I am an experienced Linux/BSD System Engineer with a broad range of experience in this field looking for work in the form of tiny jobs upto fixed employment for up to 3 days a week.

Over the last 25 years I have been tasked with setting up, configuring, securing and maintaining/monitoring a wide range of servers and server applications on different flavours of Linux and BSD. In this time I have also developed a large number of Shell, Perl and Python scripts to automate tasks, monitor services and bridging applications. Think of it as working at a small ISP, overseeing things.

Please find below a non-inclusive list of my areas of expertise to get you an idea what I might be good at and at what not so much.

Areas of expertise:
Installation, configuration, securing and maintaining of..
  • ..most Redhat and Debian derived Linux distributions (i.e. Ubuntu, Centos, Mint, Devuan, Fedora) and all three majos *BSDs (OpenBSD, FreeBSD, NetBSD)
  • ..Internet service daemons like Sendmail, Bind, Apache, Nginx, Lighttpd, Thttpd, Mosquitto, Squid, MySQL (MariaDB), Postfix, Asterisk, Sshd etc.
  • ..Cryptocoin wallets, Block explorers (Iquidus), Pool Software (Yiimp, Powerpool, MPOS), Notification scripts (Alert, Block, Wallet etc.)
  • ..Networking gear like Firewalls, Routers, Switches. I have most experience with Mikrotik Routers, OpenBSD Firewalls and iptables, but if your gear has a good manual available, chances are I will be able to work with it just fine

Writing scripts and software for..
  • ..Python backend services based on Cherrypy (and Flask to a certain degree)
  • ..Shell and python scripts for automation, security and bridging/interfacing to other systems/applications

My first education has been in electronics and I have kept that as a hobby over all the time, so I have a solid base knowlegde of electronic and electric systems. I am also able to develop simple firmware for a broad range of microcontrollers like ATmega, PIC, ESP8266/ESP32. I have also a solid knowledge and ~5 yrs experience in Eagle CAD.

I realize that the work I am looking for is all about trust and integrity, therefor I will maintain a separate unmoderated thread for people to share their experience with me and my work. I also encourage you to check my trust and post history here in bitcointalk.

When I work for you on your host(s), I am ready to record all my sessions with your host(s) for you to inspect, audit and check with the goal of being 100% transparent to you in what I did and how I did it.

My strength:
  • Commitment, persistence, experience, loyality
  • I can isolate and spot problems in complex systems quickly
  • I know exactly what I can do and what not. If I take on a task, I will be able to fulfill it.

My weaknesses:
  • Selling myself aggressively, probably too upright and honest for current times when things should like better than they are in fact.
  • Using social media, I am not on any social media, except my Twitter account which I mainly used to follow Bitmain for their new miner announcements. Otherwise I look at it as huge waste of time and refuse to use any one of these communication channels, no matter if it is Facebook, Whatsapp, Telegram, Youtube, Discord or what else.
  • Making ugly things look good, I am not at all into eye candy stuff. Ascii tables look more appealing to me than a fancy colored, fantastically stylesheeted browser tables. I can't and won't change this, I am into making things work, not making things look good

References, Links:

Payment:
  • I prefer to be paid in one of the following cryptos: BTC, LTC, DOGE but I am willing to consider other cryptos too if you insist. I am happy to use one of the well established escrows like Ognasty or philipma1957 at your expense if you would like to escrow.
  • If I will insist on escrow to work for you, I will carry the cost for escrow.
  • My prices/offers will be in USD and they will be converted with the exchange ratio of your desired crypto at the day when you place an order for my offered services.
  • Payment is due within 48hrs when the offered work has been fully delivered to you, for larger jobs I might ask you for a partial upfront payment to an escrow.
  • For jobs totalling in more than USD 50 payment you will get a legally valid, tax deductible invoice from me.

Some words of caution:
  • If in doubt if you're really dealing with me, feel free to ask me to sign something with the my BTC address (19LSKwUh8Ak6PMod5jhCbNTk1mgBmHmjUq) staked in the BTC address staking thread.
  • Never-ever send me any cleartext passwords, only exception being they are sent PGP encrypted and that key has been signed by above BTC address and plus there is a very compelling reason for you to do so.
  • I will always authenticate to your host with a 4096bit SSH private key, when I send you the public key I will always send it signed with my staked BTC address.


I look forward to receive your questions and inquiries. Feel free to post below or PM me as you see fit.

7  Alternate cryptocurrencies / Mining (Altcoins) / L3+/L3++ voltage tuning script on: May 15, 2018, 04:50:37 PM
Since jstefanop was so kind to release his demo code for voltage setting on the L3+ we could finally undervolt our L3+ and save some of those precious watts.

Though the process of tuning every hash board is time consuming and boring (at least after the third L3+) and I soon wished there was a way to automate this trial and error process similar to what General Tarkin did on the Titans.

So I hotglued some python script that does the whole process automatically and does not require you to install jstefanops binary on every single miner. But you need a Linux (MacOS might work) machine that can reach the miners you want to tune over the network.

Note: Just to be very clear: The script needs to be run from a different computer than your miner!

If you are willing to try this alpha software, head over to github and checkout my bitmain-tools repo:

https://github.com/psycodad-bct/bitmain-tools

Usage in the simplest form is just:
Code:
git clone https://github.com/psycodad-bct/bitmain-tools
cd bitmain-tools/scripts
./l3plus_autotune.py -i <your-miner-ip>

All options are printed if you supply no arguments to the script:
Code:
Usage:
./l3plus_autotune.py -i <ip>|--minerip=<ip> [OPTIONS]

Options:
 -p <adminpass> admin password if not set to 'admin'
 --password=<adminpass>
 -s <chain1[,chain2]> skip one or more chains
 --skip <chain1[,chain2]>

Examples:
Tune miner on 10.10.10.33, use '1234' as admin password and skip tuning chain 2 and 3:
./l3plus_autotune.py --minerip 10.10.10.33 -p 1234 --skip 2,3
Default usage :
./l3plus_autotune.py -i 10.10.10.33

The script may take anywhere from 30min to several hours or can even refuse to complete if your miner is too unstable. If that happens you can try to use the --skip option to skip tuning one or more chains/hashboards and set them to the best possible value manually.

I did this to save time on tuning and re-tuning my L3+ miners and thought I'd share it here.

Disclaimer:
This script has at best pre-alpha-quality (or even less) and comes as-is with no warranties at all. I have tested it heavily and to the best of my knowledge it should do no harm, but it has obviously when playing with voltages the potential to damage your miner and even if not it will probably void your Bitmain warranty.

Use completely at your own risk!

If in doubt, use the source Luke!

8  Economy / Trading Discussion / MA periods question on: May 21, 2017, 08:00:29 AM
Hi,

I am trying to learn a bit about technical analysis and am currently looking at recognizing trends from moving average. I have read that in traditional stock and forex markets people often look at 5-day versus 20-day MA (and quite a few other combinations like 10/30, 50/200 etc.). I was wondering what MA timespans/periods people use in cryptocurrency markets to spot trends or trend changes?

Thanks in advance for any suggestions and tips.

9  Economy / Computer hardware / [SOLD][CH] A2 Terminator 110M Scrypt miner on: May 10, 2017, 07:12:48 PM
I would like to sell one of my A2 Terminators (110M), buyed new and first hand from Inno directly. It is in very good condition and runs without problems on 1200MHz (and all other freq). Comes with ANX firmware.

Due to VAT and high shipping cost to anywhere outside Switzerland (which is not part of the EU!), I'd highly prefer to sell it locally.

I am looking for 0.25 BTC shipped free to any address in Switzerland or Liechtenstein.
I am open for offers from EU, though the price is then without shipping and to most closer EU countries the shipping cost is at least 0.05-0.07 BTC with UPS Express Saver, plus you will be charged VAT upon import + handling fee from forwarder for importing.

If you are interested, PM me or post here.

11  Economy / Computer hardware / 4x Gridseed G-Blade (5.2-6Mh/s) Scrypt miners for sale (Switzerland) on: April 02, 2015, 03:35:08 PM
I have 4 used Gridseed G-Blades script miners for sale. They are all in very good condition and can be run at 600-825MHz depending on ambient temperature, resulting in ~5-6Mh/s depending on pool/coin you mine on. Running at 800MHz on litecoinpool, the 4 together average at ~22MH/s.
The units come with USB cables but without power supplies, power supplies are available on request (see below).

I am asking for CHF 85.00 or 0.35 BTC per unit.

The miners are shipped from Switzerland, preferrably to Switzerland or Liechtenstein).
Shipping within Switzerland is flat CHF 10.00, insured next day delivery. Shipping outside Switzerland is done with UPS Express Saver, but can get a bit expensive (~30-60 CHF) due the weight and is not recommended. Also if shipped to outside Switzerland be prepared to pay import duties and your local VAT.

Power supplies are available together with the miner: CHF 15.00 for 230VAC-12VDC/10A desktop power supply or CHF 30.00 for 230VAC-12VDC/20A (not desktop).

If you buy more than one of them, I offer 10% discount on the unit price and shipping.

If you are interested, please send me PM.
