Buying and Selling Cryptocurrency is relatively straightforward, there are a huge number of guides available online which make the process very clear. However, storing and managing your crypto wallet can be a lot more confusing.

Whilst Crypto is stored in a wallet, there are many different types of wallet available all with different features and levels of functionality.

The vast majority of holders of Crypto use ‘hot’ wallets which are software programs which are connected to the internet at all times. They are the most readily available and the easiest to set up. This is especially true of those new to the Crypto market.

This article aims to provide the majority with some insight into the top tools available to help manage Cryptocurrency.

Here we go!

Increase Security

One of the most useful tools for managing your Crypto, especially if you are new to the market is a ‘cold’ wallet, one that it is not connected to the internet.

Currently, the most widely used and tested ones are –

Ledger Nano S

This is a smooth, strong, safe and affordable hardware wallet and one of the most competitively priced. Widely used, it is a multicurrency wallet integrated into a smartcard device.

It is very light and easy to use. To use it you simply connect it to a USB port and you are ready to go. It works on any computer, regardless of the operating system.

TREZOR

One of the best-known hardware wallets. It supports the major Cryptos so would work well as a Bitcoin Wallet or an Ethereum Wallet. There is full support for Windows (version 7 and higher), OS X (version 10.8 and higher) and Linux.

You can also use your TREZOR with Android devices which have USB On-The-Go. Trezor is considered to be one of the most secure ‘cold’ Crypto wallets available on the market today with complex security.

KeepKey

KeepKey works with the wallet software on your computer by taking over the management of private key generation, private key storage, and transaction signing. KeepKey generates a private key using its hardware-based random number generator, combined with randomness provided by your computer.

Once your private key is generated, you are given the one-time opportunity to write down a backup of your KeepKey in the form of a twelve-word recovery sentence. This is one of the simplest wallets to use an is widely available in major online retailers.

Archos

This well established French company with many years’ experience also recently launched a hardware wallet. Many of the features to be found on popular hardware wallets such as the Ledger Nano are replicated here, including the ability to generate a private key and support for a range of currencies.

Bitcoin, bitcoin cash, ethereum, litecoin, and zcash will all be supported, with more to be added. The device can also be used to add an additional layer of security to other third-party wallets.

Manage Your Portfolio

CryptoCompare

If you are one of the many people that hold Crypto across multiple wallets, then this may be the tool for you.

This is an excellent mobile app that aims to assist you to manage your portfolio of Cryptos across multiple wallets. With this app, you not only enter what your holdings are but where they are stored. This may seem like an unusual feature but, it is an excellent one.

It allows you to monitor how much Crypto you have stored in ‘hot’ wallets giving you the opportunity to move them into a ‘cold’ wallet for greater security. This can be an important thing to monitor given how rapidly Crypto values can change.

CoinTracker

This is a platform which you can also use to track your crypto across all exchanges and wallets. CoinTracker automates this process. You start by connecting it to every exchange you use (once it’s supported by the software) and can also add the public address to any wallet that holds Bitcoin, Ethereum, Litecoin, and Dogecoin.

It will automatically read the balance and update it in your portfolio. A useful tool to manage your Bitcoin wallet and Ethereum wallet in particular as these can contain very high values depending on when you entered the market!

Increase Trading Speed

SikurPhone

If you use a ‘cold’ wallet then you are aware of the disadvantages. You may not have it with you when markets change especially when you want to dispose of some Crypto quickly, or even buy more. The potential solution here is SikurPhone.

This is a very high security mobile phone with a built in Cryptocurrency wallet which can be used as a Bitcoin wallet or Ethereum wallet for example.

Don’t get caught out by the markets through your use of a ‘cold’ wallet. Take your wallet with you in this device which also functions as a mobile phone. Far more natural to carry around with you than bringing another hardware wallet that you need a computer to use!

Eidoo

Again this app adds functionality to the traditional wallet and increases trading speed. The app works by creating a mobile app that serves as a multicurrency digital wallet for Bitcoin, Ethereum, and all ERC20 tokens.

Additionally, Eidoo functions as a hybrid exchange, allowing users to sell, buy, spend and convert cryptocurrencies on one platform.

Once users download the Eidoo mobile app, they can secure all their multi-asset accounts and addresses, as well as their signing keys. Eidoo simplifies and protects wallets by allowing users to access their cryptocurrencies in one place with one password, which is comprised of 12 words.

In case of emergency, Eidoo also offers a “recovery tool” designed to provide users with their tokens in a simple manner.

A very cool app and an interesting one to watch from this Swiss start up.

Reduce the number of wallets you need

Whilst you can increase trading speed and security one of the best tools to use is a multicurrency wallet that reduces the number of wallets you need to hold. You can try these two to start.

Exodus

Exodus is designed for people who have never used an exchange. It is really simple to use and particularly good for those trading Bitcoin or Ethereum.

Exodus currently supports Bitcoin, Bitcoin Cash, Bitcoin Gold, Dash, Ethereum, Ethereum Classic, Litecoin and unusually Decred.

Jaxx

Very popular Jaxx was first developed in 2014 and serves not only as a Bitcoin wallet but an app which can store multiple cryptocurrencies such as Litecoin, Dash, Ethereum and Bitcoin Cash.

Ripple is not currently supported but the Jaxx team have hinted they may support this feature in the future.

 

That’s it!

Clearly, there are a huge number of tools out there to help you to manage your Cryptocurrency wallet. Hopefully, this article has given you a good place to start!

A simple explainer on what quantum computing actually is, and why it is terrifying for bitcoin

Most simplifies the complex process of quantum computing as “it can be 0 and 1 at the same time.” That is not an explanation for why it threatens Bitcoin. This is.

What to know:

  • Google has published research suggesting a future quantum computer could theoretically derive a bitcoin private key from its public key in about nine minutes, threatening the security of Bitcoin and other cryptographic systems.
  • Unlike classical computers, which process bits as either 0 or 1, quantum computers use qubits that can exist in multiple states simultaneously and exploit phenomena like superposition and entanglement to explore many possibilities at once.
  • This fundamentally different form of computation could undermine the mathematical assumptions behind current encryption, raising urgent concerns about the safety of existing blockchain assets and digital security more broadly.

This week, Google published a paper describing how a quantum computer could theoretically derive a bitcoin private key in 9 minutes, with ramifications that stretch to Ethereum, other tokens, private banking, and potentially everything in the world.

Quantum computing is easy to mistake for a faster version of a regular computer. But it is not a more powerful chip or a bigger server farm. It is a fundamentally different kind of machine, different at the level of the atom itself.

A quantum computer starts with a very cold, very small loop of metal where particles begin to behave in ways they do not behave under normal conditions on Earth, ways that alter what we think of as the basic rules of physics.

Understanding what that means, physically, is the difference between reading about the quantum threat and actually grasping it.

How computers and quantum computers actually work

Regular computers store information as bits — each is either a 0 or a 1. A bit is a tiny switch. Physically, it’s a transistor on a “chip” — a microscopic gate that either lets electricity through (1) or doesn’t (0).

Every photo, every bitcoin transaction, every word you’ve ever typed is stored as patterns of these switches being on or off. There is nothing mysterious about a bit; it is a physical object in one of the two definite states.

Every calculation is just shuffling these 0s and 1s around really fast. A modern chip can do billions of these per second, but it still does them one at a time, in sequence.

Quantum computers use something known as qubits instead of bits. A qubit can be 0, 1, or — and this is the weird part — both at the same time!

This is possible as a qubit is a completely different kind of physical object. The most common version, and the one Google uses, is a tiny loop of superconducting metal cooled to about 0.015 degrees above absolute zero, colder than outer space but here on Earth.

At that temperature, electricity flows through the loop without any resistance, and the current is said to exist in a quantum state.

In the superconducting loop, current can flow clockwise (call that 0) or counterclockwise (call that 1). But at quantum scales, the current does not have to pick one direction and actually flows in both directions simultaneously.

Don’t mistake it for switching between the two really fast. The current is measurably, experimentally and verifiably in both states simultaneously.

Mind-bending physics

With us so far? Great, because here’s where it gets genuinely strange, because the physics behind how it works isn’t immediately intuitive, and it is not supposed to be.

Everything someone interacts with in daily life obeys classical physics, which assumes that things are in one place at one time. But particles do not behave this way at the subatomic scale.

An electron does not have a definite position until you look at it. A photon does not have a definite polarization until you measure it. A current in a superconducting loop does not flow in a definite direction until you force it to pick.

The reason we don’t experience this in everyday life is decoherence. When a quantum system interacts with its environment, air molecules, heat, vibrations and light, the superposition collapses almost instantly.

A football cannot be in two places at once because it is interacting with trillions of air molecules, dust, sound, heat, gravity, etc., every nanosecond. But isolate a tiny current in a near-absolute-zero vacuum, shield it from every possible disturbance, and the quantum behavior survives long enough to compute with.

That’s why quantum computers are so hard to build. People are engineering physical environments where the laws of physics that normally prevent this stuff from happening are held at bay for just long enough to run a calculation.

Google’s machines operate in dilution refrigerators the size of huge rooms, colder than anything in the natural universe, surrounded by layers of shielding against electromagnetic noise, vibration, and thermal radiation.

And the qubits are fragile even then. They lose their quantum state constantly, which is why “error correction” dominates every conversation about scaling up.

So quantum computing is not a faster version of classical computing. It is exploiting a different set of physical laws that only apply at extremely small scales, extremely low temperatures, and extremely short timeframes.

(CoinDesk)

Now stack that up.

Two regular bits can be in one of four states (00, 01, 10, 11), but only one at a time (since current flows in only one direction). Two qubits can represent all four states at once, as the current is flowing in all directions at the same time.

Three qubits represent eight states. Ten qubits represent 1,024. Fifty qubits represent over a quadrillion. The number doubles with every qubit that is added, which is why the scaling is so exponential.

The second trick is something called entanglement. When two qubits are entangled, measuring one instantly tells an observer something about the other, no matter how far apart they are. This lets a quantum computer coordinate across all those simultaneous states in a way that regular parallel computing cannot.

And these quantum computers are set up so that wrong answers cancel each other out (like overlapping waves that flatten) and right answers reinforce each other (like waves that stack higher). By the end of the computation, the correct answer has the highest probability of being measured.

So it’s not brute-force speed. It’s a fundamentally different approach to calculation — one that lets nature explore an exponentially large space of possibilities and then collapses to the right answer through physics rather than logic.

A monumental threat to cryptography

This mind-bending physics is why it is terrifying for encryption.

The math protecting bitcoin relies on the assumption that checking every possible key would take longer than the age of the universe.

But a quantum computer doesn’t check every key. It explores all of them simultaneously and uses interference to surface the right one.

That is where it ties into Bitcoin. Going one direction, from private key to public key, takes milliseconds. Going the other direction, from public key back to private key, would take a classical computer a million years, or even longer than the age of the universe. That asymmetry is the only thing proving that a person is holding their coins.

(CoinDesk)

A quantum computer running an algorithm called Shor’s can go through that trapdoor in reverse. Google’s paper this week showed it could do so with far fewer resources than anyone previously estimated, and within a timeframe that races against bitcoin’s own block confirmations.

This is why the threat of quantum computers breaking blockchain encryption is genuinely making everyone very worried.

How that attack works step by step, what Google’s paper specifically changed, and what it means for the 6.9 million bitcoin already exposed, is the subject of the next piece in this series.
