1  Bitcoin / Electrum / Electrum 3.3.4 doesn't start (Linux) on: April 24, 2019, 01:41:31 PM
Hello, I'm on Ubuntu and I have upgraded my Electrum wallet from 3.2.3 to 3.3.4.
Now if I run it from the application menu it doesn't start anymore.

If I try from the command line, I get the following error:

~$ electrum
Error: No module named 'aiorpcx'. Try 'sudo python3 -m pip install <module-name>'

~$ sudo python3 -m pip install aiorpcx
Requirement already satisfied: aiorpcx in ./.local/lib/python3.6/site-packages
Requirement already satisfied: attrs in ./.local/lib/python3.6/site-packages (from aiorpcx)

~$ electrum
Error: No module named 'aiorpcx'. Try 'sudo python3 -m pip install <module-name>'

What could I do to fix it?

4  Bitcoin / Bitcoin Discussion / How to run Bitcoin Core behind corporate proxy? on: January 30, 2018, 03:59:30 PM
I'm running Bitcoin Core on TestNet and I would like to set a proxy.
Since I'm using Squid to set proxy for my system I should set "localhost:3128" somewhere... but bitcoin-qt options have only SOCK5 proxy field.

So, it can't connect...

How can I solve? Thank you in advance.

5  Bitcoin / Electrum / Using Electrum on TestNet under corporate proxy on: January 30, 2018, 12:43:24 PM
Hello, I'm trying to make my Electrum connect to server but I'm experiencing problems.

I installed versione 3.0.5 and run it in TestNet mode (`--testnet`).
I filled the proxy settings with my data but it stucks on "Not connected" or "Waiting for fee estimates"...

I also tried to connect it manually, but none works.

What could be the problem? Does exist any log to see to figure out why it is not connecting to any server?

Ieri sono venuto a conoscenza di questo topic grazie alla segnalazione dell'utente Micio.

Avrei voluto aggiungere tutti gli articoli, maggiormente pubblicati su edizioni cartacee, che mi è capitato di incontrare negli ultimi mesi, ma il topic è chiuso. Apro dunque quest'altro thread in cui magari continuare a raccogliere questo genere di articoli "spazzatura" e farci due risate!

Could be riskful to keep using OKPay?
9  Alternate cryptocurrencies / Announcements (Altcoins) / [ANN] Kairos:The first artificial intelligence driven Exchange Traded Fund [ICO] on: July 27, 2017, 11:30:49 AM
The first artificial intelligence driven ETF for block-chain assets



Kairos is the first of its kind Artificial intelligence Crypto Asset management fund. It is an exchange Traded Fund ( ETF) that is managed with Artificial intelligence from end to end. The objective of Kairos is to make better investments decisions and take well calculated risk while investing in the volatile crypto markets. This is achieved by the use of a well sophisticated A.I agent also called: Kairos.

It is predictive by nature, and analyzes mass data sets with incredible speed and accuracy. Kairos A.I manages the Kairos Fund by optimizing and harnessing the vast investment potentials available in the crypto markets.

The Kairos Fund utilizes the power of Artificial intelligence and the integrity of the blockchain to effectively manage crypto assets with the aim of increasing the Net Asset Value of investor held tokens by growing the fund.

How does it work ?

The Kairos Team comprising of 2 main entities; Rocky Mountain Ayre Inc. (RMTN) and Ocubicle Inc are initially offering 15million Kairos tokens at a crowdsale for $10 per token with the aim of raising $150 million from investors who are interested in investing in the first of its kind crypto asset fund that is completely driven and managed using artificial intelligence / Machine learning. Funds will be invested in a diversified pool of digital currencies and assets that have shown great potentials and are expected to experience rapid growth in the near future.

For full details of the Kairos investment strategy, please see section 3.2.0 in the white paper.

The token is a representation of the stake each investor has in the fund. Return on investment is split into 2 equal parts. One part is shared as dividends to investors every quarter based on the amount of tokens owned. Dividends are paid in Ethereum( ETH or BTC) depending on investors preference.

The other half of the returns is spread across the total tokens in supply. This is expected to continually increase the Net Asset Value of the investor held tokens. The Net Asset Value of the token is calculated in realtime and always displayed on the investor's dashboard.

In line with the U.S Securities and Exchange commission Rule 506 of Regulation D, Investors need to be aware that the tokens purchased cannot be sold for at least a year.

However after the first year, investors would be able to sell their tokens at the open exchanges anytime they wish. The Kairos fund would also open a buy-back window every quarter for investors that want to trade-in their tokens at the current Net Asset Value.

Why invest in the Kairos Fund ?

Kairos combines the transparency of the blockchain and the precision of Artificial intelligence.

Kairos is an AI that understands the crypto market just like humans do but analyzes the market data and trends faster than any human, hence it has the ability to make smarter and quicker investment decisions.

Kairos always asses risk against potential profit before vital trades decisions are taking.

Kairos is designed to grow the fund that it manages and constantly increase the Net Asset Value ( NAV) of the tokens purchased by investors. This is achieved by distributing half of the return on investment from the fund across the available tokens, while the other half is paid out as dividends every quarter.

Artificial intelligence is a relatively new technology in the crypto markets that brings in sophisticated reasoning. Most market investors are still unseasoned and invest mostly based on guesses, sentiments or speculations. In the last 12 months the crypto market has grown from a market capitalization of $12.4 bIllion to $106.6 billion ( as at June 2017).

Rocky Mountains Ayre Inc (RMTN) a US public company in the OTC markets and Ocubicle Inc are one of the pioneers of AI technology in the crypto market, delivering a cutting edge AI technology that maximizes the available investment opportunities while solidly managing risk.

How much does 1 Kairos token cost?

1 Kairos token costs 0.05 ETH. (About $10).

Is there a minimum investment threshold?

Yes. The minimum amount of tokens that can be purchased is 5 token which is equivalent to 0.25 ETH (Between $50 - $60).

Crowdsale (ICO) Bounties.

We have set aside 10,000 tokens as bounties.

Detailed information about our bounty categories is listed below.

Our bounty campaign is open to everyone willing to participate, and ends on August 25th 2017 by 5pm EST.

 We will distribute all bounties within 5 - 7 days after the ICO ends.

The Kairos (KRX) tokens will be distributed according to the predefined groups.  We have allocated certain amount of tokens for each group.

Twitter bounty: 2000 KRX

Follow @Kairostokens on twitter to receive our latest news and updates.

For following us you receive 10 pts per week.

Retweet our news updates to your friends and followers.

 For every retweet or mention, you get points as follows;

Under 250 followers: 5 pts
Atleast 1000 followers: 10 pts
Above 5000 followers 20 pts

Retweets are valid for tweets after 26th of July 2016.

Here is how the bounty is calculated;

For example if you follow @Kairostokens on twitter for the duration of the crowdsale and you have 1000 followers

You earn 10 * 4 = 40 pts for the 4 weeks duration

If you do 10 retweets, you earn 10 * 10 = 100pts

Total points earned: 40 + 100 = 140 pts

At the end of the Crowdsale, we will compute all the points earned by participants in this category and each person will get tokens that corresponds to the percentage of the total point earned.

If total points by all participants in this category is 14,000

The user in the example gets: (140/14,000 * 2000) = 20 KRX

18  Local / Italiano (Italian) / Bitcoin-QT v0.9.1 non sincronizza... on: April 23, 2014, 09:14:26 AM
ho riaperto Bitcoin-QT dopo una decina di giorni e mi ha chiesto di effettuare l'upgrade alla versione 0.9.1.
L'ho effettuato e ho lasciato aperto il client per fargli terminare la sincronizzazione con la blockchain: 9 giorni rimanenti.
In mezza giornata è arrivato a 7 giorni e poi ho spento il pc.
Il giorno successivo invece è rimasto sempre su 7 giorni mancanti, nonostante io abbia lasciato il pc acceso tutto il giorno!
Addirittura oggi dice 8 giorni mancanti.
E' come se non andasse avanti con la sincronizzazione.
Ho controllato lo spazio libero sul disco e ci sono circa 60 GB.

Quale può essere il problema?

Utilizzo Ubuntu 14.04.
