I am not a lawyer, but...
The Coinage Act of 1965, Section 31 U.S.C. 5103, entitled "Legal tender," states: "United States coins and currency... are legal tender for all debts, public charges, taxes, and dues."
In the USA all monetary debts can be paid in US dollars.
Second, while bitcoin is legally a payment method in the US, it does not have legal ...

I made a payment to a company for a product more than a year ago in
bitcoin. The amount that I paid then was equivalent to $75. Now the
company has failed to provide the product and they and I both agree
that I'm owed a refund. However, we disagree on the means.
The company wants to refund me - in bitcoin if I wish it - to the
value of $75 of ...

While in the US last year, I sent money to myself in Europe that way once, because it was significantly cheaper than using the legacy banking system.
I think it mostly comes down to whether you have easy access to a Bitcoin exchange from your bank account in the US and what amounts you are trying to transfer. It also depends on how urgently you need the ...

A refund should be issued using the same payment method that was used at the time of purchase.
This also serves an anti-fraud measure for the cases where a purchase was made on a stolen medium (eg a credit card) but the scammers request a refund in a different medium (eg cash) as soon as the payment goes through because all they want to do is take the money ...

I'd actually like to see a reference to someone saying that it's illegal.
...because it's legal.
FinCEN guidance establishes who must register with government and when one must pay taxes (sell bitcoin for USD, pay taxes on gains).

XBT is used because the ISO 4217 (the standard for currency codes) alphabetic code XBC is already in use. It stands for the European Unit of Account.
Here's the Official table of ISO 4217 codes
The X indicates it's not a national currency, but rather a supranational currency (like the East Caribbean Dollar, XCD) or something else that isn't quite a ...

Given that bitcoin has increased in value, one of us has to profit from this.
If you hold the bitcoins while the value goes up, you are the one entitled to profit from it, because you also risk holding while the value drops, and then you're the one stuck with the loss.
Imagine the 10,000 BTC pizza transaction were refunded now: would the purchaser be ...

Acquiring Data
You have two options here:
Check out one of the data providers online. Quandl offers (mostly) free historical data for a variety of pairs and exchanges. Alternatively, if you have bucks to spare, Coinigy offers high-quality data sets on a per-month pricing model.
Roll your own data crawler, using a programming language of your choice and the ...

There are memory intensive mining algorithms, but usually the "memory" being discussed is not of the DDR3 variety. That 64 GB of DDR3 RAM you have is an excellent resource for many computing tasks (and enough to make me jealous), but is also dramatically slower than the L1 and L2 cache physically on the chip with your CPU. This is the memory we're talking ...

In addition to the technical factors mentioned by MCCCS, it's important to consider economical factors as well.
If the problem being solved has value outside of the Bitcoin network, it allows miners to essentially "double dip" on the rewards - they earn both from the Bitcoin received as block rewards, as well as the incentive structure off chain.

The Bitcoin price is the result of a free market. There is no central authority that could by order "pump money into the system".
This currently happens anyway - but decentralized. When more people buy Bitcoins the market cap increases. With a higher market cap a single trade has a lesser effect on the price. Therefore, over time when Bitcoin attracts more ...

But then the next problem is transaction order and validity to prevent double spending. I don't understand completely why a timestamp can't just be included for every broadcasted transaction, and the transaction could have the correct, universally agreed upon time, and each ledger gets sorted chronologically. Is this because it requires a centralized system ...

There's no technical problem with making an inflationary crypto-currency. For Bitcoin, just changing the block reward schedule would do it. And there do exist crypto-currencies that have perpetual block rewards.
The thing is, the set of people who believe that inflationary currencies are good doesn't significantly overlap the set of people who think that ...

Here is a guide: How to Fork Bitcoin (create your own chain).
I really think Bitcoin as a concept is unique and powerful, and the project is well maintained by very talented developers, so I wanted to write this not just to help make it easy to clone, but to help increase understanding of the concepts and how to fully utilize them in other projects. I would ...

From Introduction on the Bitcoin wiki:
Capitalization / Nomenclature
Since Bitcoin is both a currency and a protocol, capitalization can be confusing. Accepted practice is to use Bitcoin (singular with an upper case letter B) to label the protocol, software, and community, and bitcoins (with a lower case b) to label units of the currency.
So, the accepted ...

Was there a sales contract?
https://en.bitcoin.it/wiki/How_to_accept_Bitcoin,_for_small_businesses#Contract points out the value of specifying the refund policy in such a contract.
(Personally I'd think this was a USD purchase, quoted in USD, to be refunded in USD, irrespective of how the value was transferred. But IANAL, and I'm not even American.)

The reason Bitcoin has value is because it is resistant to censorship (e.g., prohibiting transactions related to illicit purchases) and corruption (e.g., an authoritative source changing the rules). It does this thanks to the innovation known as proof-of-work.
But this proof-of-work means Bitcoin is vulnerable to attack from a party or cartel with more than ...

You probably should start from the source by yourself, look here:

2,523 forks of bitcoin. Greatest bump ever.
You should get source of 2 coins that you want to compare, and simply diff it. It is easiest way to understand what's the difference.

The price wont rise, they are issued and redeemable by Amazon. Think of it as loyalty points you would receive from your local supermarket to use later rather than a cryptocurrency.

Taking your questions in order:
How yet another "currency" will solve anything, or what Bitcoin is supposed to be solving?
Because this is a currency that has different properties that avoid the properties of other currencies that create these problems. For example, the supply of Bitcoins is fairly precisely defined and nobody can devalue them through ...

ASICs (Application-specific integrated circuits) are especially manufactured for one specific hashing algorithm. Therefore, a Bitcoin ASIC using SHA-256 will not work for Litecoin or Dogecoin as they both use Scrypt. One example for ASICs are the Butterfly bitcoin miners.
There are altcoins that also use SHA-256, such as Freicoin, Peercoin or Namecoin. An ...

Bitcoin is a "proof-of-work" based cryptocurrency. Proof-of-work based cryptocurrencies are protected from a malicious 51% attack because of that coin's mining network.
Bitcoin is protected by 12,500 Th/s of mining capacity (using SHA hashes). For an attacker to come in and attempt to commit "double spend" fraud (as the result of having 51% of the mining ...

With such fast main memory, I'm sure your machine would be pretty good for mining MemoryCoin whose proof-of-work algorithm, Momentum, requires a lot of RAM. Copied verbatim from its tech page:
Each hash requires 1GB of Memory to perform and encrypts 50GB of data.
By contrast, the verification only requires 128K and less than one

How do you transfer your potatos into rice?
You go to market, find somebody who wants to "transfer" his rice into potatos and exchange it with him. There's no direct way of transfering one commodity into another (except perhaps alchemy).
So no, you can't transfer cryptocoins across different cryptocoin daemons, that's impossible.
But there's plenty ...

To organize a wire from Europe to the US and back using bitcoin without fees, you can:
Open an account on KRAKEN.com do a IBAN/BIC wire to your kraken account (free!), takes 2-4 business days
Open an account on circle.com and register your US bank account
Buy bitcoins on kraken.com (very small fee, usually around 20 eurocents)
