Investors boost the amount of gold in their portfolio as uncertainty increases, making fear the key medium to short-run driver, Goldman said. Wealth is the long-term driver, especially in emerging markets such as China, where growing income levels over the next few decades will support prices, it said in a report. :-
Bitcoin has put in a phenomenal performance this year, soaring toward $6,000 after starting the year around $1,000. In contrast, gold is up 12 percent. The bank listed several characteristics to compare them, adding that it’s focusing on the currency, not the blockchain technology.
Unit of account: Gold is better at holding its purchasing power, and has much lower daily volatility. Bitcoin/dollar volatility has averaged almost seven times that of gold in 2017, the bank said.

In March of 2010, an enterprising early Bitcoin adoptee named “SmokeTooMuch” offered to sell 10,000 bitcoins for $50. No one took them up on their offer. At the time, Bitcoin was worth almost nothing for more than a year. No markets existed to exchange bitcoins. Few people actually knew about or used the cryptocurrency. Bitcoin existed as little more than a really cool idea and nothing more.
Around May and June of the same year, the cryptocurrency became worth around 1 U.S. cent. As more people learned about the technology behind cryptocurrencies, Bitcoin’s value grew until it was worth one U.S. dollar in Spring of 2011.
Now, Bitcoin is worth roughly $2700. SmokeTooMuch’s $50 offer would be worth $27 million today.BTC The cryptocurrency has seen rises, crashes, and everything in between. Yet in the last month, the cryptocurrency increased by a whopping $600+ in value.
But how did this new currency grow so fast in such a short amount of time.

Banks are reluctant to work with bitcoin, that fact has been well known in the community for some time. Until now, though, few concrete reasons have been given as to why.

New statements from a senior banking practitioner in Australia working in anti-money laundering (AML) and counter-terrorism financing (CTF), compliance could go some way to providing an explanation.

Banks around the world, particularly in the US, have been closing down accounts of bitcoin startups and even bitcoin-accepting businesses for over a year now. Even those that do work with bitcoin businesses are reluctant to be named in the media.

It is a purely digital creation created by open source software that mines for new Bitcoins using highly complicated computational algorithms. It also has a fixed quantity. Once a certain number of Bitcoins are created, no new ones can be made. It is due to this combination of factors that a Bitcoin is such a hard investment commodity now. :-*I really like Bitcoin. I own Bitcoins. It's a store of value, a distributed ledger. It's a great place to put assets, especially in places like Argentina with 40 percent inflation, where $1 today is worth 60 cents in a year, and a government's currency does not hold value. It's also a good investment vehicle if you have an appetite for risk. But it won't be a currency until volatility slows down."

Gold has the same value all over the world. This is due to the fact the people all over the world want gold. However, the same cannot be said about Bitcoin. Only a select number of investors are interested in it. This is a crucial point when comparing crypto currencies to precious metals. :-\However, such opportunities are quite rare unless you are talking about pyramid or Ponzi schemes. The reality is that there is such an investment opportunity that currently exists and it’s called Bitcoin. This is a very exciting investment opportunity that is not based on reality. Below is the market cap of $5 billion for Bitcoin, only half the market cap when compared to gold.

Whether you go for a game night at your friend’s house or are relaxing with friends after work, invariably someone will be talking about the next big investment option.   :-*In the past, these discussions were around real estate, stocks, even gold. Now, all such talk is about cryptocurrencies. To be more specific, all such talk is around bitcoins. There is good reason for this interest, every alternate month in 2017 has seen the value of bitcoin hit all time highs. On 31 October 2017, bitcoin breached the Rs5 lakh mark, giving speculator returns of 844% in the last 1 year.

Some countries are also exploring the idea of introducing government-backed cryptocurrencies, which would take them one step closer toward fiat-currency status.
As Russia, India, and Estonia are considering their own digital money, Dubai has already taken it one step further. In September, the kingdom announced that it has signed a deal to launch its own blockchain-based currency known as emCash.
So ask yourself, how can you effectively hedge against a fiat money system with another type of fiat money? BTC

First, don't confuse the terms "offline" vs. "online", use "bitcoin wallet" and "bitcoin account" instead. All wallets that are not considered "cold storage" are "online" because they are connected to the internet.
Bitcoins reside in the block chain.BTC
A bitcoin account is an account with some service (such as an exchange) that holds bitcoins for you. They hold the keys to the bitcoins in their wallet and your account keeps track of how many of the bitcoins in their wallet are supposed to be yours.

It's value increase or decrease like everything else it's value increase with increase in number of buyers and decrease with increase in number of sellers. :-\that depends on the many factors underneath.you can see it's value getting doubled from the last year with increasing number of users and it's going to go even higher in the future with more people Getting aware and willing to invest in it.

Some of the negative effects of technology can be linked to the effect it has on sleep habits. We get sucked into online activities that keep us up too late and the constant stream of information can make it difficult to turn off our brains. Also, the ambient glow from screens can affect the release of melatonin, the sleep chemical. Keeping technology out of the bedroom would be a very healthy habit to acquire.

What we mean by that is bitcoin is made for the Internet-generation. We are quickly moving past the days of carrying around paper cash or pulling out your credit card. Bitcoin goes several steps further than the convenience of credit cards by equipping users with a payment option that is significantly lower in fees, provides virtually instantaneous transaction time, and is accessible through the dozens of bitcoin wallets.

One can earn money (dollars/pounds/euros) by working, selling things, or exchanging other currencies.  ::)Similarly, one can earn bitcoins by mining (working in virtual world), getting paid in bitcoins for selling goods, or purchasing bitcoins by exchanging existing currencies (like US dollars). Earned or purchased bitcoins reside in safe wallets, which are online secure bitcoin storage provided by bitcoin service providers. Wallet owners can use bitcoins for any transactions where the counter party accepts bitcoins. Every transaction gets recorded onto the bitcoin network (through block chains), which authenticates the transaction....

Bitcoin is but the most famous example of an emerging technology network with the potential to improve banking. It belongs to the new type of financial animal called crypto currencies, i.e. decentralized, secure money storage and money transfer enabled by the Internet. What Bitcoin, and the even more promising Ripple network do, is not to poke a hole in banking’s basic business models—lending, deposits, trading, and money exchange—but to create the embryos for entirely new markets typically referred to as the Internet of Value. That is, a way for regular folks, as well as specialists, to potentially monetize everything, regardless of location, traditional market access and jurisdiction.

In order to truly destroy Bitcoin an attacker would have to destroy every copy of the Bitcoin blockchain. With tens of thousands of copies of the Bitcoin blockchain stored across the global many believe the only way to do this is global nuclear war.   While the Electromagnetic Pulse (EMP) and subsequent fireball would wipe many hard drives clean there are undoubtedly a number of copies of the blockchain stored in Faraday Cages and safes that would be protected from the EMP.  
So its means it is not possible to Kill Bitcoin....
