Bitcoin: What are the biggest threats to Bitcoin?

Ripple may be the latest craze in the cryptocurrency world. Although its price still lags far behind Ethereum and Bitcoin,  it has nonetheless gained 3800% in recent months,  catapulting it to the number 3 spot on the list of over 100 cryptocurrencies with regard to market capitalization. What's more important, perhaps, is the technology that Ripple offers aside from its currency. The Ripple blockchain protocol has gained recognition by more than 60 major financial institutions around the world, with the National Bank of Abu Dhabi one of the latest to incorporate it into its practices. Ripple has, in this way, broken a barrier that virtually no other cryptocurrency has, by finding a way to integrate itself within the broader financial world. To some, this spells a new way for the future of the digital currency industry. To others, though, Ripple has some significant security weaknesses. That could be a threat not only to Bitcoin but to all those cryptocurrencies that are r...

What is the future of the IOTA cryptocurrency?

Well, I personally am don't see a bright future in IOTA cryptocurrency. Let's see the whole story. IOTA  is a distributed ledger for the  Internet of Things . The first ledger with microtransactions without fees as well as secure data transfer. Quantum proof. IOTA is ~$0.62 at the moment. Market capitalization is around $1.1b. Circulating supply of ~$2.7b MIOTA. Maximum supply of ~$2.7b MIOTA. So what exactly is IOTA IOTA is a new cryptocurrency that focused on Machine-2-Machine (M2M) transactions. The main purpose of IOTA is to serve the machine economy by enabling feeless M2M (Machine-to-Machine) payments. IOTA provide efficient, secure, lightweight, real time micro-transactions without fees.  It is open-source, decentralized cryptocurrency, engineered specifically for Internet of Things, its real-time micro transactions and providing ecosystem that is ready and flexible for scale. It is denoted by MIOTA i.e. 1 million IOTA as a unit. There is no tr...

How can I make money with Ethereum?

It's simple you can start investing (buying and selling) in it. See the chart. Did you observed something in it? Let me tell you… It falls a little and then it grows to high. Buy-the-dip and Sell-the-rip. Do this method whenever it falls.

Do I have to get a specific setup to mine a specific cryptocurrency, or can I use a generic setup to mine most/all of them?

There are many options for cryptocurrency mining. Some algorithms can still be run more or less 'effectively' on CPUs (eg, Cryptonight), others work best on GPUs (Ethereum, Zcash, Vertcoin), and still others are the domain of custom ASICs (Bitcoin, Litecoin). But besides having the hardware, there are other steps to take to get started with mining. In the early days of Bitcoin and some other cryptocurrencies, you could effectively solo-mine the algorithms. That meant downloading (or even compiling) the wallet for a particular coin and the correct mining software. Then configure the mining software to join the cryptocurrency network of your choosing, and dedicate your CPU/GPU/ASIC to the task of running calculations. The hope was to find a valid block solution before anyone else. Each time a block is found, the calculations restart, so having hardware that can search potential solutions more quickly is beneficial. These days, a lot of people forego running the wallet soft...

Why cryptocurrency is growing so exponentially in recent years?

Lets compare the physical currency and cryptocurrency. Fiat Money(Currency) Issued by government. Unlimited supply and can be produced more by the government when necessary. Physical way of exchange money. Form of coin or paper. Centralized and control by the law and banks. It's value is determined by the market and regulation. Cryptocurrency (Bitcoin) Created by computers. Limited supply and has a set of maximum. A digital way of money exchange. Presented by private and public piece of code. Decentralized and not controlled by any single entity or government. It's value is not determined by the supply and demand. Do you still think the money that can be controled by you or any independent people need not to be growing?

What is the NEO cryptocurrency, and what does it represent?

NEO, formerly known as AntShares, is generally known as the " Ethereum of China ." But an even more accurate description of the project would be " China's public blockchain ," according to the company. NEO made news when it went from being a top 15 cryptocurrency to a top 10 cryptocurrency as of the time of this writing. NEO's token value surged from sub-$10 to more than $20, and its market cap to more than $900 million. NEO's platform is similar to Ethereum's but has some clear advantages and a different overall mission. First of all , it provides various advanced languages for its compiler, such as Python and Go. Second , and more important, its NEO Contract (which is run through a NEO Virtual Machine) supports various commonly used programming languages, such as C# and Java, which is a major advantage. This makes its barrier to entry for new developers much smaller than other platforms', as they do not need to learn new languages to c...

Could a quantum computer crack the private keys of a bitcoin address?

A looming concern in the crypto community is whether  quantum computing will destroy Bitcoin’s underlying protocol. There are two main reasons why bitcoiners should be skeptical about quantum computing threats to blockchain technology. First , Bitcoin’s encryption is not wholly vulnerable to quantum computing.  Satoshi Nakomoto  knew about the possibility of stronger computer power being able to penetrate encryption, and that is why he built the protocol to withstand attacks. Second , even if a government agency or other organization possessed the talent to bust Bitcoin’s encryption, they would likely forgo the opportunity.
