Abra is a bitcoin-based digital wallet app that lives on your smartphone. It is the easiest way to buy, sell, store, send and receive bitcoin from anywhere in the world. It’s similar to a brokerage, but it’s also a wallet. Abra supports bitcoin as well as over 50 global currencies which means you can convert in and out of bitcoin or any available currency, easily. You can also send bitcoin to anyone who has a bitcoin or an Abra wallet and receive bitcoin or money.
Since very few countries in the world are working on regulation of Bitcoin and Cryptocurrency in general, these exchanges can be shut down. This happened in China sometime in September 2017. Exchanges are also at risk of getting hacked and you might lose your Bitcoin if you store it on an exchange. You can read about the biggest Bitcoin hacks here.

These days, however, Roger Ver is advocating for Bitcoin Cash. In a recent interview with Cointelegraph, Ver described Bitcoin Cash as ‘the real Bitcoin,’ claiming it will have the bigger market capitalization, trade volume and user base in the near future. He has also been quoted saying that he holds the majority of his cryptocurrency funds in Bitcoin Cash, which is, perhaps, the biggest indicator of his faith in the asset.

Now Bitcoin Cash's camp of big-block dissidents is about to divide once again. The schism pits the maintainers of the leading Bitcoin Cash implementation, called Bitcoin ABC, against Craig Wright. Wright is one of the most controversial figures in the bitcoin world. He has claimed to be bitcoin founder Satoshi Nakamoto, but his claim is doubted by a number of bitcoin insiders—Ethereum founder Vitalik Buterin has labeled Wright a "fraud."

When thinking about how to invest in Bitcoin, you must always consider the cons of investing. The price of Bitcoin changes all the time. However, these aren’t just small changes. For example, after Bitcoin hit its highest price of $19,839 on the 17th December 2017, it dropped to $12,015 on the 22nd December. That’s a total loss of $7,824 in just 5 days!

Howdy, Welcome to popular Cryptocurrency blog 'CoinSutra'.

Bitcoin uses peer-to-peer technology to operate with no central authority or banks; managing transactions and the issuing of bitcoins is carried out collectively by the network. Bitcoin is open-source; its design is public, nobody owns or controls Bitcoin and everyone can take part. Through many of its unique properties, Bitcoin allows exciting uses that could not be covered by any previous payment system.
Design issues. Despite Bitcoin's massive rise in popularity over the past several years, it is not immune to design problems. For example, starting late last year Bitcoin transaction speeds became very slow because of a scaling problem related to the way the Bitcoin blockchain works. (You can read the details here.) That issue did not end up creating the existential crisis for Bitcoin that some analysts predicted, and the problem has now more or less been solved via something called SegWit. Still, the Bitcoin scaling issue was a reminder that a new type of serious problem may creep up in the future that undoes Bitcoin.
In mid July 2017, mining pools and companies representing roughly 80% to 90% of bitcoin computing power voted to incorporate a technology known as a segregated witness, called SegWit2x. SegWit2x makes the amount of data that needs to be verified in each block smaller, by removing signature data from the block of data that needs to be processed in each transaction, and having it attached in an extended block. Signature data has been estimated to account for up to 65% of data processed in each block, so this is not an insignificant technological shift. Talk of doubling the size of blocks from 1mb to 2mb in November has ramped up, and is expected. This would also go some ways in improving bitcoin’s scalability. In mid-October, Bitcoin scientists from Bitcoin Unlimited revealed they had mined the world's first 1GB block, 1,000 times bigger than the normal size. 
A hard fork is when developers and miners no longer agree on a proposed change to the software, despite operating on the same blockchain. Once the fork takes place, one group of so-called nodes — computers that are connected to the network and are part of the transaction confirmation process — will upgrade to the new software and the other will operate on the old rules, creating two separate blockchains and digital currencies.
Though in some cases reluctantly, most other Bitcoin Cash implementations have sided with Bitcoin ABC. The biggest of these, Bitcoin Unlimited, has made its latest release compatible with the Bitcoin ABC hard fork by default — though users can configure their software to be compatible with Bitcoin SV instead. Other Bitcoin Cash implementations, such as Bitprim and Bcash, are also compatible with Bitcoin ABC.
“Blockchain is a system of automated trust,” answered Trevor Welch, Chief Investment Officer at International Blockchain Investments (IBI). “We currently live in a world where some economies lack trust and transparency, others, like the US, apply it manually and with high cost and financial burden as well as a significant degree of human error. As a result any global economy can benefit from processing transactions that are verified and validated on a distributed public ledger.”
Bitcoin Cash was forked from Bitcoin and therefore has a similar infrastructure supporting it. BCH implemented larger block sizes than Bitcoin to fix network congestion, and they have gone on to be the most successful Bitcoin offshoot. Bitcoin Cash wants to compete with other payment processors like PayPal and Visa in terms the number of transactions they can process on the network.

This option is most similar to using a credit card but without the associated risks of interest rates. You can use a standard debit card that is connected to your checking account, or you can buy a prepaid card. Using a debit card is widely accepted on most exchanges and instantly transfers, meaning you won’t have to worry about Bitcoin prices fluctuating before the transfer is complete.
Like any speculative investment, buying bitcoin at sky-high valuations is risky business. If you’re asking, “Is it smart to invest in bitcoin?” you might do well to heed this advice from billionaire investor Mark Cuban, who told MONEY, “It’s still very much a gamble.” You need to know that your bitcoin investment might lose money. If you’re not prepared to face that prospect, bitcoin investment might not be for you.

Bitcoins are “mined” by people solving problems with computers. In the beginning, the best way to make money from bitcoins was to mine them with a home PC. However, bitcoin mining becomes more difficult the more miners there are. Today, you need specialised hardware, and you need to join a “mining pool” where large numbers of miners work together and share the results. Coins are not pure profit because of the cost of the hardware and the electricity consumed when mining. Also, you don’t know what bitcoins will be worth when you start mining them.

One of those exchanges, Poloniex, argues pre-trading gives the crypto community the power to decide which coin they want to support. “We believe the responsible thing to do in this case is remain neutral and allow the community to decide which chain to support, and we want to empower the community to demonstrate their support through trading activity,” Poloniex said in a press release.
Cryptocurrency markets are jittery ahead of a high-stakes "hard fork" of Bitcoin Cash. Rival factions are pushing different, mutually incompatible versions of the spinoff cryptocurrency, and the two versions are scheduled to create separate, competing versions of the blockchain starting on Thursday. The schism could create confusion among users and damage the reputation of the cryptocurrency.
As such, transactions will look identical on both chains. This means that a Bitcoin ABC transaction can be re-transmitted (“replayed”) on the Bitcoin SV chain, having users accidentally spend both. And the other way around: Bitcoin SV transactions can be replayed on Bitcoin ABC. When Ethereum Classic and Ethereum split without replay protection in 2016, this caused significant losses to unprepared exchanges, like Coinbase. Therefore, this time many exchanges and other service providers will halt withdrawals and/or deposits for some time.
See investing is one thing and living in India does offer ways to invest in Bitcoins through coinsecure but it’s price volatility and the way it is rising does ring alarm bells as it can go down by huge margins any time. What kind of an opinion you have on regulation of Bitcoins in India ? What kind of a future you see for Bitcoins in India especially after being a part of the Blockchain Summits?
First of all, bitcoin is one of about 1,500 digital currencies available and is most well-known since it has the largest market cap. Bitcoin was created to undermine the bank-dominated financial system and to streamline capital market activities. It was "mined" via supercomputers by programmers incentivized by an award of bitcoin, mostly located in areas like Inner Mongolia and Ireland, wherever electricity is cheap.

Bitcoin Cash (BCH) is a hard forked version of the original Bitcoin. It is similar to bitcoin with regards to its protocol; Proof of Work SHA-256 hashing, 21,000,000 supply, same block times and reward system. However two main differences are the the blocksize limits, as of August 2017 Bitcoin has a 1MB blocksize limit whereas BCH proposes 8MB blocks. Also BCH will adjust the difficulty every 6 blocks as opposed to 2016 blocks as with Bitcoin.

Design issues. Despite Bitcoin's massive rise in popularity over the past several years, it is not immune to design problems. For example, starting late last year Bitcoin transaction speeds became very slow because of a scaling problem related to the way the Bitcoin blockchain works. (You can read the details here.) That issue did not end up creating the existential crisis for Bitcoin that some analysts predicted, and the problem has now more or less been solved via something called SegWit. Still, the Bitcoin scaling issue was a reminder that a new type of serious problem may creep up in the future that undoes Bitcoin.
Bitcoin Cash (BCH) is released on 1st August 2017 as an upgraded version of the original Bitcoin Core software. The main upgrade is the increase in the block size limit from 1MB to 8MB. This effectively allows miners on the BCH chain to process up to 8 times more payments per second in comparison to Bitcoin. This makes for faster, cheaper transactions and a much smoother user experience.
Tom Lee, the chief analyst of Fundstrat Global Advisors, noted that Bitcoin is currently trading around 30 percent below its 200-day moving average — which is a “pretty positive signal.” The analyst also said that the “probability of making money is over 90 percent within six months” if you manage to buy BTC when it’s trading 30 percent below its 200-day moving average.
An institute will be set up within Phore to develop long-term e-commerce solutions, investments and partnerships. Its aim is to strengthen and sustain Phore, allowing it to quickly react and pivot to challenges in the future. Phore Labs, part of the Phore Foundation, will work as an incubator / seed investor, primarly identifying potentially cutting-edge digital services and products. These will be sourced from individuals, universities, start-ups and cooperatives around the world.
Like email, bitcoin is a protocol. Where email is a protocol for sending messages over the internet, bitcoin is a protocol for sending money over the internet. The bitcoin protocol defines the rules of a payment network, called bitcoin, that uses a currency, also called bitcoin, to pay computers around the world for securing the network. The software that implements the bitcoin protocol uses a special branch of mathematics called cryptography to ensure the security of every bitcoin transaction.
