Criptomonedas, un problema de falta de adopción

El de las criptomonedas es un problema en el que confluyen economía, política, tecnología y emociones encontradas. Y los análisis se basan en “partidarios” y “detractores”, cuando lo que debería haber es un análisis puramente técnico del asunto, no un debate ideológico.

Las criptomonedas (en concreto Bitcoin) estaban llamadas a generar una nueva economía con más libertad y oportunidades para todos. Pero el hecho cierto es que -de momento- han “amplificado” muchos vicios del sistema fiat: especulación, dinero sin respaldo real, burbujas, etc.

A estas alturas un porcentaje sustancial de negocios debería estar usando Bitcoin en sus operaciones al igual que el público: es evidente que eso no está ocurriendo.… Read more...

Altcoins With the Most Lucrative Potential in 2021

In early 2021, the price for altcoins was spectacular but the bulls are not evergreen. Altcoins are accounted for more than 40% of the total cryptocurrency market, with over 10,000 cryptocurrencies and counting. The explosion of decentralized finance and smart contracts give rise to some of the altcoins’ value. The highest altcoins by market cap remain to be Ether, Tether, Binance Coin, and even Dogecoin. The total market capitalization of altcoins, excluding Bitcoin, is at a all-time high, according to CoinMarketCap.

5 Unconventional Career Tips From Top Women In Data Science

Everything we do today relies on and/or uses data in some way or another. Research on any topic – from covid to climate to investing to your favorite sports team. Your smartphone. Your computer. Searching terms in Google or Bing or Yahoo or on Twitter or Instagram or on any website or platform. The list goes on and on and on…

Those searches use terms and algorithms programmed into it by someone – and 82% of the time, that person is a male (and white).


12. Crypto-craze,, A Flavor of PrimeNet

In case you’ve missed it, there has been a tremendous number of news stories, social media posts and the like on Bitcoin, Hashing Algorithms, Blockchain, video graphics cards and Crypto-mining.  If you are anything like the most of us, the information barely provides you a platform to have a discussion about the topic.  But what does it all mean?  What is a Blockchain?  What are hashing algorithms?  How does one mine for bitcoins or any other crypto-currencies?  Is it as profitable as most say?  These and many other questions will be addressed in this blog.

PrimeNet – For the past few years, I’ve really been intrigued with the application of prime numbers in public key encryption algorithms.


Ethereum Vs. Bitcoin: Whose Side Are The Machines On?

Both blockchains are relatively close to one another in terms of market cap, with Bitcoin currently holding around $170 billion. The two blockchains each have their own strengths and weaknesses, and it’s hard to say who will eventually win the race. The race for the Eureka! Moment is the point in time when a new system or technology becomes so popular that the momentum begins to shift. Bitcoin’s strengths are in its decentralized and censorship-resistant nature, which allows it to be more secure and stable.

JPMorgan Chase will give all clients asking investment advice, not just the wealthiest, the chance to trade cryptocurrency funds, according to Business Insider.

Although clients have been pressing banks for access to crypto through their accounts, JPMorgan would be the first to grant the request.

The bank’s advisors will not be allowed to recommend investments in crypto but will be able to execute purchases and sales if a client requests them. 

Funds approved by the bank for trades include Bitcoin Cash Trust, Grayscale’s Bitcoin Trust, Ethereum Classic, Ethereum Trust, and Osprey Fund Bitcoin Trust, according to an unnamed bank insider cited by BI.


Notes on Bitcoin

People could not use an operating system until Windows appeared. With icons and a mouse you no longer needed to post or learn lines of code. Same is happening with crypto. Bitcoin needs an ‘abstraction layer’ for people to understand it and go mainstream.

Alice wants to pay Bob for his services and both have their own wallet. Transaction is initiated then Alice´s wallet proposes the BC to change his status to show his wallet emptier and Bob´s fuller. The network goes through several steps to confirm this change. The proposal propagates through the net and at the same time the different nodes check that Alice has in fact the BTC she is spending.… Read more...

Bitcoin needs no entities to acknowledge it, incorporate it, regulate it, or and tax it

By 1999 Friedman predicted Bitcoin stating that internet would reduce government power and introduced the idea of digital cash, in order to reduce the power of a third party in transactions. Decentralization is a big headache for good and bad governments.

Bitcoin is inherently anti-establishment, anti-system, and anti-state. Bitcoin undermines governments and disrupts institutions because bitcoin is fundamentally humanitarian. There’s an elimination of 3rd party intrusion. It’s purely peer-to-peer.

The blockchain is free speech. It’s decentralized, voluntary, and non-aggressive. Bitcoin is not supposed to work within our current mechanisms. Bitcoin needs no entities of authority to acknowledge it, incorporate it, regulate it, and tax it.… Read more...

The value of Bitcoin does not come from some arbitrary value, and therefore people trade it. It’s quite the opposite: because anyone can trade with BTC (anywhere, everywhere with no fraud and very low fees), that as a result it has value.

With bitcoin, we can trust the people, not one man. We can trust that 51% of us are honest. We can trust that we, collectively, can make the best decisions where our own money is concerned and not one faceless bureaucrat. We can trust that the same rules apply to all.

It is a mistake to think that the BTC gets its value from the energy needed to manufacture it.… Read more...

Bitcoin and the Internet of Assets

Bitcoin is Internet 3.0, and it will not only revolutionize money, but also revolutionize the transmission of value online as we know it.

The arguments around scaling and transaction fees are relatively myopic as the network has shown time and time again — scaling solutions will be adopted, and quickly.

Some of the best developers in the world are looking to build an open world, and have strong financial incentives aligned with that goal.

Beyond remittances and money use cases, BTC represents a transition to a phase of digital assets. A world where your ‘online real estate’ will carry as much weight to you, financially and socially, as your brick and mortar home.… Read more...

¿Dinero Separado del Estado?

Se debe huir del debate ‘Criptografía vs Ley’ porque es una falacia. La Criptografía nos interesa a todos, y no hay derecho a que el Gobierno demande una ‘puerta trasera’ a los gadgets con el fín de espiar a la gente.

Hacer las comunicaciones más inseguras sólo beneficia a los responsables políticos, pero perjudica a la sociedad, haciéndola mucho más vulnerable a los ataques y atentados de ‘los malos’. Este tema es es clásico debate seguridad vs privacidad, que claramente va ganando el primer bloque ya que se asume por defecto que todos somos terroristas, piratas.

Los criminales siempre tendrán privacidad: es una de sus esencias.… Read more...

Crypto Regulation: a False Problem

(Regulate the cars as if they were horse cars).

The problem isn’t whether there should be regulation or not: no one is stupid enough to participate in a network where there are no rules or regulations of any kind. And that’s certainly not the case with Bitcoin.

Bitcoin rules are not imposed from a desk. They emerge from the network itself. For the first time, there’s a technology that allows the participants of a network to agree on rules, and to participate in the network according to those rules.

Therefore, it is not a problem of regulation vs. non-regulation. It is a problem of the nature of the regulation.… Read more...

No Bitcoins out of the Blockchain

There is not a single Bitcoin or Satoshi outside of the Bitcoin Blockchain. All transactions are kept there and the only thing that transfers is the access keys. I hear many people talk about what is safer to ‘store’ Bitcoins, a software or hardware wallet but that’s misleading because there are no Bitcoins stored anywhere else other than on the Blockchain. How and where you keep your keys is up to you.… Read more...

Blockchain: The fusion of a Database with a Network

To some, the blockchain architecture is a breakthrough because it constitutes the first large-scale fusion of a database with a network.

The Networked Database

Frst we had isolated databases, then we created the internet to connect databases to the network, and with the blockchain we are essentially merging both concepts in a completely secured and reliable way.

So at the basis of everything we have a peer-to-peer network of nodes who all run a special piece of software that can store data, run some transactions to update the data, and connect with its peers to download and spread new data.… Read more...

Money is Broken… How to Fix it?

This are the things about money that should be fixed both in the “real” and the crypto economy:

Nature of Money. Money should be a mean of exchange and settling acounts NOT a merchandise whose price is controlled by an elite. Right now even Bitcoin prices are manipulared. Money is a mean of settlement to help an economy to be liquid. It should not be a merchandise whose price and manufacturing is controlled by an elite with some kind of Old World capitalist advantage (sorry Bitcoin miners, its nothing personal).

Money should be an asset in itself, not somebody´s liability.

Native value.…

Suministro limitado o ilimitado de dinero

Las monedas con valor intrínseco son una antigualla del pasado. El dinero debería tener un suministro como el de cualquier commodity.

Lo que no es tolerable es que (al igual que ocurre con las commodities) ese suministro primario lo acaparen y se beneficien de él unos pocos, como ocurre ahora mismo. Y esto también ocurre con el Bitcoin, ya que los mineros cuentan con ventajas de capital inducidas por el ‘viejo mundo’.

China por ejemplo cuenta con el 71% de la capacidad de minado de Bitcoin en el mundo. No es extraño que cada cierto tiempo aparezcan autoridades americanas diciendo que los inversores en esta moneda corren el riesgo de perderlo todo.… Read more...

Porqué Bitcoin es Deflacionario

A medida que el valor del Bitcoin se incrementa el número de ellos necesario para comprar algo disminuye. Esto es el modelo deflacionario, que llevará a que Bitcoin termine siendo una “meta moneda” y que en en la práctica sólo se utilicen sus fracciones.

Un segundo factor refuerza la tendencia deflacionaria: el hecho de que si pierdes tu monedero con las claves el dinero se pierde para siempre (nadie lo reencuentra ni se pone de nuevo en circulación). Esto implica que la tendencia sea a que las monedas desaparezcan a medida que la gente las pierde.

Pero por contra, el hecho de poder dividirlos para siempre hace que el sistema pueda seguir funcionando igual con fracciones cada vez más pequeñas.… Read more...

El Dinero y la Última Batalla por la Privacidad

Hace años que algunos dábamos por hecho que habría regulación para todo el mundo de las criptomonedas. De una forma u otra los gobiernos y sus verdaderos amos (los organismos internacionales) tratarían de adelantarse a los acontecimientos creando ellos mismos sus propias monedas electrónicas.

Poca gente es realmente consciente de lo que implica dinero electrónico controlado de forma centralizada por los gobiernos. Junto con el de la salud o la información es uno de los pilares del estado orweliano que nos preparan hace mucho.

Para introducir alternativas a Bitcoin, y una vez terminado con éxito el experimento el sistema pondrá a toda máquina su potencia represora mediante la cultura, los medios, la fiscalidad, etc.… Read more...
