1  Alternate cryptocurrencies / Altcoin Discussion / Re: Anonymity, Security and Privacy: Anonymous Cryptocurrency Enhancement Comparsion on: January 21, 2018, 10:33:21 PM
The following is an updated attempt to assess and evaluate:

  1.   Enhancements/Protocols:
  
    a. Anonymous Capabilities / Anonymity
    b. Privacy
    c) Security

  2.   The coins that currently implement these features


Every will be made to assume none of these coins are a complete solution (yet).  Not because they're bad, but because a lot of the other comparison threads out there have been polarized toward one coin as the "solution with all the best end to end features".  

I would really appreciate your thoughts and input on this work in progress, so that together, we can make it even more complicated and unreadable.




Anonymous, Privacy, and Security features are clearly all related to one another, yet in my mind are distinct:
  
Anonymous features ultimately aim for the holding and transacting of a commodity which both requires and releases zero identifying information.
              Buy a pizza.  No receipt, no exchange of information, no record of the pizza or you.
                    There are obvious legal implications to this, causing it to be a "dark" feature.
                          However, this slander assumes that the governing body itself is not "dark", or corrupt.   In many places in the world, Anonymity is a matter of life and death.
                          As such, Anonymity is a double edged sword, aiding both sinister and altruistic efforts.
                          https://en.wikipedia.org/wiki/Anonymous_(group)
              

Privacy features aim to give ownership of identifying information to individuals/entities who hold or transact a commodity.
              Buy a pizza, there's a record of it but that record is for you (and potentially the pizza shop) only.
                    There is a legal arguement for privacy features.  https://en.wikipedia.org/wiki/Privacy_law

Security:  If you can hack the thing, you need not worry about Anonymity and Privacy.  Those are out.

Awesome work, SafeCoins !

If you don't mind a suggestion, it would be nice to have a column telling if all transactions are private or there may be non-private (transparate) transactions. It is a feature having pros (transparency may be interesting in some cases) and cons (if few people use the privacy feature of the coin, it exposes the private users)
2  Alternate cryptocurrencies / Altcoin Discussion / Re: Somebody should make a movie about Satoshi on: October 21, 2017, 07:39:07 AM
It could be about the IRS, Federal Reserve, Scotland Yard, MI6 and the FBI searching, investigating and going around the world, trying to track down Satoshi. They come across Craig Wright and other imposters. They find a Satoshi Nakamoto in California and demand that he confesses. It turns out that this is the wrong Satoshi. There are car chases, only to catch criminals mistaken for Satoshi.

We walk into the NSA data center with a group of programmers. In front of big screens with scrolling code, they talk about new algorithms that they developed for their new quantum computer, which will try to geo-locate Satoshi's public addresses. One programmer says: "This is the most hash power ever executed by a supercomputer any where in the world" Behind them, we see a huge room with multiple rows of computers. We can hear a loud hum from the heat fans. Another programmer walks over to the wall and turns the air conditioning to maximum. A superior says: "We got congress to give us $2 billion to catch him. If his doesn't work, you're all going back to writing iOS apps for kids."

At the end of the movie, the investigators are standing around a hotel lobby, tired, frustrated and sharing notes. The superiors are yelling obscenities at the incompetent subordinates. Behind them, we see a man with sunglasses, seated and sipping on cognac. He is surrounded by beautiful women. It looks like a scene out of a Dos Equis commercial of the “world’s most interesting man.” He gets up nonchalantly, walks to the front of the hotel, where a bellhop drives up in a Lamborghini, gets out and hands the keys to the man.

So close, yet so far.

The man turns his head, looks back at the investigators and smirks. He gets in the Lambo and starts the engine. The camera zooms in on the keychain, which has a name tag with the initials “SN”. He drives away with a loud roar.

Fade to black.

It made me think of this: https://www.youtube.com/watch?v=hkDD03yeLnU

Hello,

I'm quite newbie to the bitcoin system, so my below theory might be nonsense... But I would like to know your opinion about it:

Given that:
- Bitcoin transfers are public
- We may know the addresses used by the main exchanges: people sending or withdrawing money must know them
- The transfers in/out of those addresses may be monitored

Would it be possible to deduce:
- If exchanges addresses are transferring money out --> people withdrawing money to hodl --> less offer --> price rises
- If exchanges addresses are receiving money --> people getting ready to sell --> more offer --> price falls

Would that be possible?
If so, is anyone already doing this kind of analysis? I didn't find any thread about it.

I don't know if this is possible

Even if you could carry out this type of analysis, I don't think you would get any coherent results since, to me, it is pretty meaningless anyway. How come? Simply because when people sell and buy at exchanges, they don't typically withdraw the proceeds. They just sit idly and wait for the price to rise (fall) in order to sell (buy) again, then rinse, repeat (and reap profits). And this happens many times until the trader decides to withdraw, so there is no way there could be a meaningful correlation between prices rising (falling) and the number of transactions made to and from exchanges. Hope this helps

But people shall withdraw their bitcoins from the exchange if they want to avoid losing them if the exchange closes, like Mt. Gox.

I agree that those doing trading will keep their money in the exchange, but cautious holders shall withdraw.

Another person here interested in Bitcoin investment  Wink

I think there are lots of newbies like me attracted by the +1800 USD rise this month.

IMO, it is an interesting investment if you can afford to lose the money. And if it becomes the future of economy, it will have a huge increase potential !

However, I fear that if people just invest into it and never spend the money, it will make the Bitcoin economy to fall into a deflationary spiral, with a potentially harmful effect for it..
6  Economy / Economics / Bitcoin as a way of avoiding to change money when travelling abroad on: August 26, 2017, 09:38:43 AM
If you travel abroad from time to time, you are probably used to change money: to do so, you have to find a change office and accept the rates they offer. Many of them also ask to pay a fixed-amount fee, they want more money than what they get from the fx rate.... If it is a touristic place, there may be a little competition from different change offices, at least, if they don't agree prices. But in general, as an individual, you have very little power, you can't hardly negotitate, only accept what they propose... On the other side, if you choose to withdraw money from an ATM with your credit card, you will be paying the FX rate your bank decides to apply to you, with potentially other fees...

However, if Bitcoin become an accepted currency in shops worlwide, we could avoid to change money to the local currency. We will still need to change from OUR currency to Bitcoin, but I feel that we have a much larger negotiting power on that:
- you can do it anytime from your home
- you may automatically buy Bitcoin with a given limit at interesting rates, intead of accepting the prices proposed by a few change offices in the area
- you may have already created a Bitcoin wallet and be used to it: you will automatically understand if a price in a shop is cheap or expensive because you are used to see prices in bitcoins, instead of having to translate into your currency...
- you may keep the remaining money in Bitcoins and still be able to use it when you are back home, etc...

Bitcoin would work as a parallel universal currency, a situation that already exists with USD in many countries, where it is used in parallel with the local currency.

But of course, prior to that, it will need to become widely accepted and have a more stable price

What do you think? Have you ever used bitcoin when travelling abroad?
