The private key (comparable to an ATM PIN) is meant to be a guarded secret, and only used to authorize Bitcoin transmissions. Thus, it’s the “private key” that is kept in a Bitcoin wallet. Some safeguards for a Bitcoin wallet include: encrypting the wallet with a strong password and choosing the cold storage option, i.e. storing it offline. In the case of Coinbase, they offer a secure "multisig vault" to host your keys, which you can sign up for. 

Bitcoin Cash is a cryptocurrency.[4] In mid-2017, a group of developers wanting to increase bitcoin's block size limit prepared a code change. The change, called a hard fork, took effect on 1 August 2017. As a result, the bitcoin ledger called the blockchain and the cryptocurrency split in two.[5] At the time of the fork anyone owning bitcoin was also in possession of the same number of Bitcoin Cash units.[5]


Second, bitcoins are not traded on Wall Street. They cannot be bought or sold through a brokerage. Instead, one must set up a bitcoin "wallet," which can probably best be thought of as a bank account exclusively for bitcoins. Once this account is set up, its holder can link to a traditional banking account and use those funds in local currency to buy and sell bitcoins.
Even as the existing payments system in developed countries becomes ever more convenient and secure, the space is still littered with middle parties taking a small amount from each transaction. These players include payment processors, payment networks, issuing banks, and acquiring banks. The dream of bitcoin and other monetary systems based on blockchain technology is for payers to be free of these inherent costs of exchanging currency for goods.

Finally, as everyone who held Bitcoins before the split received an equal amount of Bitcoin Cash tokens, some people voiced their concerns that the split was nothing but a money-making scheme. In fact, the hard fork did create a situation similar to a double-spending problem, as it made conducting two transactions from a single wallet using the same set of keys possible.

Bier’s prediction is based on the reality of the situation rather than personal feelings regarding the technicalities of the upcoming hard fork. It is an informed and wizened view. The economic majority in a cryptocurrency is, in real terms, as important as the mining majority. There are a lot of reasons for this, not the least of which is the cost of the hardware involved in mining cryptocurrencies.
That being said, it isn’t perfect. One of the most pressing issues for the cryptocurrency has always been its scalability. More specifically, it’s been the size of a block of transactions, which upon the creation of Bitcoin was limited to one MB. This limit causes substantial delays in transaction processing times and limits the number of transactions the network can process.

Ver has put his weight behind the new software upgrade, or the current Bitcoin Cash. But Wright — the Australian computing genius who has on a number of occasions claimed to be Satoshi Nakamoto, the pseudonym given to the creator of bitcoin — argues the software should deviate toward the original bitcoin, hence Satoshi’s Vision (SV), by raising the maximum block size to 128MB from 32MB.
The appeal for many is the fact that Bitcoin is decentralized, meaning no specific group or governing body has control over it. Instead, it is secured by advanced cryptography, a set of military-grade encryptions, and regulated by a network called the Blockchain. The Blockchain acts as a digital ledger, confirming buyer/seller funds and establishing the order in which transactions take place.

SEARCHING FOR information on YouTube about bitcoin will immediately lead to a flood of promotional videos, some with Bill Gates' face on the logo and a "Bill Gates talks about bitcoin" tagline. Not surprisingly, when you click on it you won't find Bill Gates or Warren Buffett, but the same message of "hop on the bitcoin wagon before it's too late."
Miners take financial risks on hardware with the reasonable expectation that they will be able to earn a return. If one or the other chain is better equipped to service that result, then that will become the preferred chain of miners, and if they are within a few dozen dollars of each other in unit price, this preference can fluctuate algorithmically in ways that can have a dramatically negative effect on everyday users as difficulties rise and fall and make block times irregular.
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. 
Since its inception, there have been questions surrounding bitcoin’s ability to scale effectively. Bitcoin is a cryptocurrency that exists within a network of computers, within the blockchain. This is revolutionary ledger-recording technology. It makes ledgers far more difficult to manipulate for a couple of reasons: The reality of what has transpired is verified by majority rule, not by an individual actor. And this network is decentralized; it exists on computers all over the world.
Documentaries can be a great way to learn more about a subject. Especially for a subject as complex as Bitcoin, a good documentary which presents relevant information in a compelling cinematic format, will greatly accelerate learning and recollection. If you’re interested in Bitcoin and looking to learn more about it; like how it works, its history, the people or companies involved, and so on, then we have several great documentaries to recommend!

Bitcoin Cash is a proposal from the via BTC mining pool and the Bitmain mining group to carry out a UAHF (User Activated Hard Fork) on August 1st 12:20 pm UTC. They rejected the agreed consensus (aka BIP-91 or SegWit2x) and have decided to fork the original Bitcoin blockchain and create this new version called “Bitcoin Cash”. Bitcoin Cash can be claimed by BTC owners who have their private keys or store their Bitcoins on a service that will split (BCC)/BCH for the customer.

Bitcoin functions as the "reserve" currency of cryptocurrency. So it is very hard to buy other coins without first buying bitcoins. Once you purchase the bitcoins you can convert the bitcoins into other cryptocoins. This is mostly because Bitcoin has very good liquidity and is traded on every cryptocurrency exchange. So most coins are traded against Bitcoin rather than the US dollar or other fiat currencies.
