COSS Exchange and COSS Token - A Full Summary

Let me get started by stating I am no way involved with the COSS team. I simply am a COSS holder who wants to share this coin with others. Please note, I am writing this without an opinion and just stating facts (I will include a portion below with my opinions and an explanation of my thought process). Everything I say can be double checked with some DD and if I have time, I will come back and link said facts!
What is COSS?
What does COSS do?
What is the payout formula?
When are payouts?
How do you receive payouts?
What is the total supply?
What is the current marketcap?
Where can I buy COSS?
My opinions:
1) COSS, based on numbers, is simply undervalued. For a token that already has an existing functional product, its marketcap is well below what it should be. Trading volume has also increased significantly in the past few days! Imagine receiving profits from an exchange like Bittrex or Binance I urge you to browse their website and look at everything for yourself to make your own judgement!
2) There is a lot of work to be done on the exchange, but it is just getting started and is still in Beta. Good things take time. I remember when Binance first began and the struggles it went through, and look at it now. I have faith COSS can do that same. Currently, the things I believe that need to be fixed are exchange UI upgrades to make them more appealing to the eye and deposit/withdrawal times.
3) There is a lot of concern about COSS being a scam due to the team's association with VRS. I definitely had to look into this and found that Rune, on of the founders, addressed this concern. For me it was a satifactory explantion stating that VRS was not a scam, but a failed project. Please read bullet 4 to get the link to the full statement and other FAQ's
4) There are tons of FAQ's and known issues that are being asked about COSS. These two links pretty much cover them all at the moment. Each link has some different information, so please read both!

Easy UASF Node in Debian VM tutorial

So if you have a moderately powerful gaming desktop with a Quad-Core CPU like an i5 or better and 8+GB of RAM, you can easily run your own little UASF node in the background. Once it's done syncing with the network, you won't even notice it's there. Here's how.
You will need :
The following assumes you know how to install Linux in a Virtual Machine
Step I. - Installation. Go through expert install and set up a base system with only ssh server enabled. For partitioning, you can do just one big disk and everything in one partition, but if you happen to have a computer that has both SSD's and HDD's, it would be optimal to create two virtual disks and use a small one for the OS on the SSD and a larger one on the HDD in a custom mount point for the blockchain. Reboot and ssh into the server.
Step II. - Build requirements. A few things need to be taken care of. First, you'll want to edit the /etc/network/interfaces file and set up a static IP. Once that's done, stop by your router and make sure that traffic on port 8333 is forwarded to your debian VM. Then, install some packages we need :
apt update apt upgrade apt install build-essential autoconf libssl-dev libboost-dev libboost-chrono-dev libboost-filesystem-dev libboost-program-options-dev libboost-system-dev libboost-test-dev libboost-thread-dev libevent-dev git libtool pkg-config 
The next one is a bit more annoying. We need Berkeley DB 4.8, and it's a little old. It's packages are in the Debian Squeeze archives, so in the /etc/apt/sources.list file, we need to add :
deb http://archive.debian.org/debian/ squeeze main 
Then remember to update again, and install the thing :
apt install libdb4.8++-dev libdb4.8-dev 
If you intend to also throw on xorg and a UI, you will want Qt as well. Otherwise skip this last step.
install libqt4-dev libprotobuf-dev protobuf-compiler libqrencode-dev 
Step III. - Build time
#Starting from /home/yourUser git clone https://github.com/UASF/bitcoin.git -b 0.14-BIP148 cd bitcoin ./autogen.sh ./configure make make install 
That's it! Well, mostly. Start it with
bitcoind -daemon -disablewallet -datadir=/whereveyou/want/youblockchain 
...and wait about thirty hours to sync with the network. You may want to visit the /whereveyou/want/youblockchain directory and create a permanent bitcoin.conf in there. To enable RPC calls to the server and get it to accept bitcoin-cli commands you'll want to use it to create a usepassword and copy that to your user's /.bitcoin/bitcoin.conf.
Minimal bitcoin.conf example
daemon=1 listen=1 disablewallet=1 server=1 rpcuser=bob rpcpassword=bob's password 
Security I recommend you disable password login and use private key authentication only on ssh, and also restrict iptables rules to the bare minimum that must be allowed for this application. You will need this in your iptables script :
# Allows BITCOIN traffic from anywhere -A INPUT -p tcp --dport 8333 -j ACCEPT # Allows RPC calls to the bitcoin server from localhost -A INPUT -p tcp -s 127.0.0.1 --dport 8332 -j ACCEPT

[uncensored-r/CryptoCurrency] COSS Exchange and COSS Token - A Full Summary

The following post by ychok is being replicated because some comments within the post(but not the post itself) have been openly removed.
The original post can be found(in censored form) at this link:

The original post's content was as follows:
Let me get started by stating I am no way involved with the COSS team. I simply am a COSS holder who wants to share this coin with others. Please note, I am writing this without an opinion and just stating facts (I will include a portion below with my opinions and an explanation of my thought process).

What is COSS?
  • coss.io stands for Crypto One Stop Solution. Essentially, COSS is doing a lot. From their own exchange, to their own markets, a payment gateway for businesses to accept crypto as payments, and even more planned on their roadmap, COSS has a lot on their plate. The ICO ended a few days ago at a rate of 1 ETH for 6000 COSS making the price about 5 cents a COSS.
What does COSS do?
  • Well as an exchange (no its not decentralized), COSS charges fees for trading. COSS also charges fees for their marketplace or using their payment gateway plug-ins. 50% of the total revenue they obtain is distributed to the COSS tokens weekly. The way it works is that the crypto that was received in revenue as a fee is what is distributed. Example: If the total trading volume on the exchange is 100,000,000 for the week and Ether was 20% of that volume and BitCoin was the other 80%, the payout will be 80% in bitcoin and 20% in ether.
What is the payout formula?
  • [(Daily Trading Volume) x 7 x 0.002 x 0.5]/93 mil = payout per coin. Multiply this by how many COSS you hold for the value of your payout, but remember the payout will be in a plethora of coins that are traded on COSS!
When are payouts?
  • Payouts occur EVERY Sunday (weekly), with the first payout to be this Sunday (October 8th). I am not sure what time of day this will occur.
How do you receive payouts?
  • The simplest way to receive payouts is by holding COSS tokens in your COSS wallet on coss.io
  • You can receive the payout if you hold COSS on MEW, but it requires additional steps in order to have those coins be a part of the payout. If you use MEW you need to do a bit of configuration. Use this tutorial: https://coss.io/coss-token-revenue-share-tutorial
What is the total supply?
  • Currently, the circulating supply is 93 million. 80 million of this 93 million are token holders, 10 million is set aside such that the revenue generated by these 10 million tokens goes to charity, and the last 3 million are used by the team to payout bounties and such. (Coinmarketcap has yet to be updated, request has already been sent in)
What is the current marketcap?
  • At a rough price of 15 cents per coin, the marketcap for COSS is around 14 million
Where can I buy COSS?
  • At the moment, COSS is being traded on coss.io, etherdelta, and HitBTC
My opinions:
1) COSS, based on numbers, is simply undervalued. For a token that already has an existing functional product, its marketcap is well below what it should be. Trading volume has also increased significantly in the past few days! Imagine receiving profits from an exchange like Bittrex or Binance I urge you to browse their website and look at everything for yourself to make your own judgement!

[TUTORIAL:] Creating a custom wallet. Part 1: Proof of concept.

Download and view this tutorial on GITHUB
I'm teaching myself the technical aspects of Bitcoin. I decided to start by making a custom wallet. Here is my quick and dirty proof of concept using Python, bitoinrpc, and PyQt.
So far, this only queries bitcoind for getinfo. It's only a stepping stone to the greater application.
I'll make more tutorials as the program develops. Please feel free to comment and ask questions. Keep in mind, Python isn't my primary language. I decided to go with Python only because I could use the practice.
I wrote this using Linux. It should work on Windows / Mac, but your mileage may vary. To use this, you are going to need Python 2.7 installed on your machine (obviously) as well as the dependent libraries: PyQt, Python bitcoinrpc, and json. Copy and paste the code in a file somewhere and run
$ python  
Change "rpc_username" and "rpc_password" to match that of ~/.bitcoin/bitcoin.conf
Make sure ./bitcoind -server is running
If everything is set up correctly you should see a gui app appear with the same information as if you were to run bitcoind getinfo from the command line.
#!/usbin/python # -*- coding: utf-8 -*- import sys from PyQt4 import QtGui from bitcoinrpc.authproxy import AuthServiceProxy import json class Configuration(): def __init__(self): self.protocol = "http" self.username = "rpc_username" self.password = "rpc_password" self.ip = "localhost" #self.port = "18332" self.port = "8332" def get_uri(self): self.uri = self.protocol+"://"+self.username+":"+self.password+"@"+self.ip+":"+self.port return self.uri class Command(): def __init__(self): self.conf = Configuration() self.access = AuthServiceProxy(self.conf.get_uri()) def get_info(self): self.info = self.access.getinfo() #self.info = self.access.listaccounts() return self.info class UI(QtGui.QWidget): def __init__(self): super(UI, self).__init__() self.init_ui() def init_ui(self): command = Command() info = command.get_info() keys = info.keys() label = [] line_edit = [] for (i, key) in enumerate(keys): label.append(QtGui.QLabel(str(keys[i]))) line_edit.append(QtGui.QLineEdit(str(info[keys[i]]))) grid = QtGui.QGridLayout() grid.setSpacing(10) for (i, item) in enumerate(label): grid.addWidget(label[i], i, 0) grid.addWidget(line_edit[i], i, 1) self.setLayout(grid) self.setGeometry(300, 300, 350, 300) self.setWindowTitle('getinfo') self.show() def main(): app = QtGui.QApplication(sys.argv) ex = UI() sys.exit(app.exec_()) if __name__ == '__main__': main() 
Features of note:
In the future I may just link to a github account. Time permitting.
Let me know what you think. Thanks!
