Blockchains and shared ledgers let different companies, organizations or other entities rely on the same source of customer data and other personal information — one that’s secure, auditable and looks the same to each party. Money is used as a measure of payment for trades and goods. Usually, when you pay someone or take payment in your bank account, it’s the bank or credit card company which keeps count, stores the transaction, and records it for future reference. These are your third-party intermediaries. It is also a reference for yourself, as to how much money you still have left. Here you are dependent on the infrastructure of banks, notaries, governments, accountants, and others to tell you how much you have. Now imagine a digital ledger where you can record the transactions you conduct with either the Bitcoin currency or any other digital asset: A collective ledger where the book-keeping is neither closed nor under the control of one party.

one of the reasons Bitcoin was developed was to provide the everyday person an alternative means of storing value or transacting. Another would be taking some control over ones savings/earnings, which previously could not be done. Bitcoin is the first (better) alternative to the existing monetary system outside of precious metals and plain old barter. Moreover, Bitcoin creator Satoshi Nakamo even embedded a Financial Times headline into the first transaction of a block

China has also reportedly issued specific instructions as to how the exchanges should close, according to leaked documents reported by Coindesk. China’s crackdown on cryptocurrency also includes bans on Initial Coin Offerings, or ICOs, about which several additional countries have expressed concerns. Bitcoin’s sharp drop comes after rising uncertainty in the Chinese market, with two major Chinese currency exchanges, China BTC and ViaBTC, having announced that they will halt trading by the end of this month.

You can get Bitcoin by exploiting them or exchanging on trading floors in conventional currencies. The value of Bitcoin lies in its properties. Like a conventional currency, it is a medium of exchange, a unit of calculation, and a place of value. Gold is clearly a unit of calculations. It is measured and valuable compared to all the currencies we use everyday. Gold is a medium of exchange. Gold is a core element of the central bank's reserve assets. Gold is still appreciated in the global trading environment, especially in times of crisis. This was Iran, Greece, Venezuela demonstrated using to pay for the debt.

Security refers to a negotiable and fungible financial instrument having a specific monetary value. It culminates to ownership rights via stock in publicly traded company or having a creditor relationship with corporation or government body or ownership rights in the form of option. Thus only a very ICO’s will make it to the security category with the above mentioned specifications to adhere to. However SEC will be in a place to take the ultimate call regarding setting of criteria.

I think, the most important part of life is Freedom. Freedom from politics, banks, religion anything you _choose_. Bitcoin and technology is about freedom. It has the opportunity for everyone to show their talents, joke, develop, rearrange, build and draw anything you like and share it with the world. You cannot be afraid of sharing your point.

Bitcoin is a worldwide peer-to-peer electronic cash system, known for low and predictable transaction fees, reliable confirmation times, and useable instant transactions. Unfortunately, because many network nodes continue to enforce a limit on the size of blocks which is below today's demand (the current limit corresponds to roughly 3 transactions per second), fees have risen, backlogs of transactions have formed, and confirmation times have become erratic. A smaller number of nodes have even adopted replace-by-fee policies to permit double-spending of transactions stuck due to the backlogs, which has produced the regrettable side effect of making instant Bitcoin transactions less secure.
Bitcoin Unlimited will be activated when the majority of the miners signal their approval. The fact that a simple the majority of miners can dictate the longest chain (and that the longest chain "wins") is the fundamental truth of Bitcoin's "Nakamoto Consensus" mechanism. Bitcoin Unlimited recognizes this. Although you may have heard that Segregated Witness (SW) activates at a 95% vote, this activation level is simply a convention. The truth is that if 51% of the miners wanted a change, they could simply mine only the changed blocks, and reject all unchanged blocks. Since 51% is the majority of the miners, the changed chain would be the longest, and therefore the "winner".
To bootstrap this new digital currency, it takes investors like you willing to hold bitcoin through the ups and downs of its price action. You want to be rewarded for that risk. By supporting Bitcoin Unlimited you are supporting our objective to return control over Bitcoin's evolution back to the market and our efforts to enable node operators to lift the block size limit that is presently restricting transaction volumes. By removing this limit, Bitcoin's user base will be free to grow, and with it its market capitalization.

Transactions can be instantaneous if they are “zero-confirmation” transactions, meaning that the merchant takes on the risk of accepting a transaction that hasn’t yet been confirmed by the bitcoin blockchain. Or, they can take around 10 minutes if a merchant requires the transaction to be confirmed. That is far faster than any inter-bank transfer.
Some merchants will charge a fee for debit card transactions too, as they have to pay a ‘swipe fee’ for fulfilling them. Bitcoin transaction fees are minimal, or in some cases free.
With bitcoin, you own the private key and the corresponding public key that makes up a bitcoin address. No one can take that away from you (unless you lose it yourself, or host it with a web-based wallet service that loses it for you).

The People's Bank of China (PBOC) was among the number of government authorities to deem ICOs as an unauthorized fundraising method. This is certainly the Chinese state laying down the law and threatening all and sundry. The cryptocurrency crackdown was expected to be due to "unreasonable abuse" in the Chinese market.

Nice planning, but the Law of large numbers overrules everything. i.e. In a large sample size, unknown no. of consecutive losses is possible for whatever probability. There are people on this website who have posted that no matter how thorough your price analysis, your entry into a trade is never better than 50-50. These people are not traders.

There are at least three ways, though only one of them looks rational today. First, you could mine your own bitcoins. Second, you could buy some from an exchange. Third, you could buy shares in a fund that has invested in bitcoins. The problem is that people can make money by buying things that are essentially worthless, such as used postage stamps, Beanie Babies, and (historically) tulip bulbs. Tulipmania operated on the “bigger fool” theory, also known among stock traders as “momentum investing”. For example, tulip bulb prices may be insane but they keep going up. I may be a fool to buy them, but I expect a bigger fool to buy them from me. Simply replace “buy low, sell high” with “buy high, sell higher”. This works until you run out of fools.

It appears the bitcoin price continues its bullish path which started during the second half of 2016. Although there have been a few stumbles along the way, bitcoin continues to set higher prices every month. It is evident other traditional assets have a problem keeping up with the bitcoin trend right now. Gold has been stumbling a bit as well, even though it will always have a specific appeal to investors worldwide. While this heavy resistance is trying to disrupt bitcoin’s price gains, one thing has become obvious. Bitcoin is currently more valuable than one ounce of gold. Although this may seem like a silly comparison to financial experts, it goes to show there is a legitimate demand for bitcoin, whereas interest in gold continues to wane as time progresses. It is not impossible the gold price will show some bullish signs along the way as well, although all eyes are on bitcoin for the time being.

I doubt that there is any other cryptocurrency or altcoin that can supersede the bitcoin. 
But it dosen’t really replace the coins as they still give their function in their own blockchains, it is just that when you can use one blockchain as control panel of every other chain. For some new kind of money to come along that can do the same to bitcoin it would have to be so advanced that we cannot imagine it today. I believe telepathy would be required, or it may be be based on some kind of data that can be sent faster than light.

Cash is being displaced in so many ways that it’s hard to keep track. There are credit cards and electronic payments; apps such as Venmo, PayPal and Square Cash; mobile payments services; cryptocurrencies that operate outside the purview of central banks; and localized offerings such as Kenya’s mPesa, India’s Paytm and Bangladesh’s bKash. These innovations are encouraging cashlessness across communities worldwide. Cash will likely become less popular, thanks to the high cost of using cash and the growing array of alternatives. But I expect it will remain with us forever. The future will be “less cash,” rather than cashless.

I choose investing strategies buy and hold: Buy and hold investors believe "time in the market" is a more prudent investment style than "timing the market." The strategy is applied by buying investment securities and holding them for long periods of time because the investor believes that long-term returns can be reasonable despite the volatility characteristic of short-term periods. This strategy is in opposition to absolute market timing, which typically has an investor buying and selling over shorter periods with the intention of buying at low prices and selling at high prices.

The buy-and-hold investor will argue that holding for longer periods requires less frequent trading than other strategies. Therefore trading costs are minimized, which will increase the overall net return of the investment portfolio.

Sure, you might argue bitcoin is newer and flashier, and that it has arguably more utility in the digital era than gold. But, gold has the indisputable track record, having been a cherished store of value for thousands of years across human civilizations.
However, bitcoin's traits have led to those backing the cryptocurrency to believe it could potentially unseat gold over the long haul.
Another key advantage bitcoin has over gold is that its supply level is fixed and transparent – eliminating fears of the typical inflationary pressures associated with overproduction that could diminish the value of the asset.

While the future of cryptocurrencies is uncertain, the accusations levied at them by banking executives may say more about the execs than the crypto — do these higher ups truly believe what they are saying or are they members of an unscrupulous industry that’s desperately afraid their era of (relatively) free reign over the economy is coming to an end? As we consider the future of Bitcoin and other cryptocurrencies, the important thing to keep in mind is that while these systems could eventually become corrupt, many of the big banks critical of them already are.

As you can see, This is not the best time to buy HSR, That should be a few days ago.
Water flow is exhausted so the pump must rest

The countries where bitcoin will just cripple themselves and their economies. Most countries will only levy Bitcoin instead of bans.
If my country forbids bitcoin, I will transfer it bitcoin into cash in many different ways and start using them.
I hopefully, all of the countries all over the world will embrace bitcoin and make it as the world currency, that way, every transaction that we are going to have will be more fast and convinient.
