What is Monero?

Monero has created a cryptocurrency that is truly anonymous. The sender is anonymous, the receiver is anonymous, and the amounts are anonymous. Monero has other competition in the “privacy coin” space such as ZCash, and Dash. At the time of writing, the technology behind Monero appears to be superior in its ability to be private, fungible, and decentralized.

What problem is Monero solving?

Monero is best understood in comparison to Bitcoin.

Bitcoin is a decentralized digital currency. With Bitcoin you can send money to anyone in the world without a middleman (e.g. You can send money online with a free open source bitcoin wallet and without having to involve a bank). In contrast, Monero was started in 2014 as an alternative currency to Bitcoin…

According to the Monero team there are two problems with Bitcoin:

1. Bitcoin is traceable — Every bitcoin transaction is recorded on a public ledger. You can’t see the sender and recipients names, but you can see their wallet addresses. So bitcoin is not fully anonymous, most people refer to Bitcoin as being pseudonymous (or mostly anonymous). Listen to The Bitcoin Hunter on the Reply All podcast to learn about how a Bitcoin analytics company called Chainalysis is able to trace some bitcoin transactions in less than 30 minutes.

2. Bitcoin is not fungible —

What does it mean to be ‘fungible’?

Fungible: The property of a good or a commodity whose individual units are essentially interchangeable.”

The US dollar is mostly fungible. For example, you and I could exchange 1 US Dollar, and each dollar is equal. 1 dollar = 1 dollar.

Bitcoin is not fungible Because Bitcoin is traceable, there have been attempts to block, or blacklist bitcoin that comes from addresses where Bitcoin has been stolen, or gained illegally.

How does Monero solve Bitcoin’s problems of traceability and fungibility?

Monero is untraceable — Every Monero transaction, by default, obfuscates sending and receiving addresses as well as transacted amounts.

Monero is fungible — Because it is untraceable, Monero cannot become tainted through use in previous transactions. This means Monero will always be accepted without the risk of censorship.

Monero is private — Monero is often referred to as a “privacy coin” due to it’s untraceable and fungible qualities.

Monero hardware wallets:

At the moment there aren’t any hardware wallets available for storing Monero. Although Monero support is available through the Ledger Wallet’s roadmap and could be coming in 2018.

Monero storage at cryptocurrency exchanges

You can store your Monero at a variety of exchanges such as Bitfinex and Binance. However, it’s not advisable to leave a large amount of coins on an exchange as all exchanges are an at-risk point for hackers, regulation, and third-party negligence.

Monero full node storage and paper wallet storage

The safest way to store Monero is with Monero’s full node. When you download the Monero full node you’ll be downloading the entire history of Monero to your computer — so you’ll need at least a few gigabytes worth of disk space.

Monero also offers a paper wallet storage, and a web wallet. Read more about Monero storage options on the official Monero website.

Monero’s technology

Unlike other cryptocurrencies, Monero is not a fork of Bitcoin, it is a fork of the CryptoNote protocol. The Monero team has created three new technologies in order to make Monero transactions completely anonymous:

Monero competitors

Dash and ZCash are often listed as the two coins competing with Monero to become the “privacy coin” of choice.

Bitcoin vs. Litecoin

bitcoin vs. litecoin

Bitcoin and Litecoin are both cryptocurrencies. Today, money is created and managed by individual countries (e.g. the US issues USD, England issues pounds, etc). Bitcoin and Litecoin are revolutionary because the founders have created a global currency that can be used by anyone in the world, and isn’t tied to any country.

Bitcoin was announced in 2009 via an online academic paper. Two years later in 2011 Litecoin was forked (aka. copied) directly from the Bitcoin code because Litecoin’s founder Charlie Lee believed Litecoin could make some adjustments to the code that would offer consumers lower fees, and quicker transaction times.

The innovation behind both Bitcoin and Litecoin is that they allows two people to send money on the Internet without a third party (like a bank). For example, at the moment I can send you money via Paypal, Citibank or Bank of America, but in all of these scenarios we are trusting these companies to manage our transaction. The problem with this current system is that banks take fees to manage our money, and banks are being attacked by hackers daily. Bitcoin and Litecoin allow you and me to exchange money without using a bank, and without relying on a company.

Today, Bitcoin is often regarded as a store of value (similar to how the gold is valued as a global store of value), and for sending higher amounts of money (think: like a wire transfer), rather than for small casual transactions. Litecoin is often regarded as a currency for day-to-day transactions. The popular analogy is that: if Bitcoin is gold, Litecoin is silver (or a credit card).

Bitcoin is:

  • A decentralized global digital currency
  • Stored on a public ledger (known as a blockchain) where each transaction takes 10 minutes to clear (to be approved)
  • Developed by Satoshi Nakamoto — an unknown figure or group of people

Litecoin is:

  • A decentralized global digital currency
  • Quicker than Bitcoin because transactions take 2.5 minutes to clear
  • Developed by Charlie Lee (aka SatoshiLite)

Takeaway: Bitcoin is more like digital gold, whereas litecoin is often thought of as a digital cash.

Coinbase is the easiest place to buy both bitcoin and litecoin. If you want slightly lower service fees and a more robust interface, then Gdax (a site owned by Coinbase) offers an alternative to Coinbase.

How much does it cost?

Cryptocurrency prices are constantly fluctuating given the supply and demand. To keep an eye on bitcoin, litecoin, or any other altcoin (an altcoin is coin other than bitcoin) head to coinmarketcap.

bitcoin vs. litecoin: How many tokens are available?

  • The max supply of Bitcoins is 21 million. Every 10 minutes a new block of bitcoin is generated. The final Bitcoin will be mined 2140.
  • The max supply of Litecoins is 84 million. Every 2.5 minutes a new block of litecoin is generated.

bitcoin vs. litecoin: What can I do with them?

Bitcoin is trending towards a replacement of gold as a store of value. Whereas gold exists with mass and weight in the physical world, bitcoin is an improvement to gold because it can be split into into very small fractions, and instantly sent to people, businesses, and banks around the world.

Litecoin is promising to replace cash. Due to its lower price and faster transaction times, it’s the perfect solution for buying a coffee, tipping a YouTuber, or gifting a friend or family member.

How to store bitcoin and litecoin:

Both web wallets, and hardware wallets exist for Bitcoin and Litecoin, and there are a multitude of options ranging high to low levels of security.
