There are other ways you can incorporate "bitcoin stock" into your portfolio as well. The Bitcoin Investment Trust (GBTC) is one notable option that operates similarly to an exchange-traded fund. It is a trust that owns bitcoins it is holding, and by buying shares of it, you can essentially bet on bitcoin value without actually owning any of your own (their bitcoins are secured using Xapo, Inc. as storage).
Even industry experts who believe that bitcoin is not a sustainable monetary unit think blockchain technology could radically change the way financial transactions are facilitated in the future. The benefits of this system are that it is transparent, secure, and streamlined, so that there are less parties involved in facilitating each and every transaction. 
The would-be hard fork with an expanded block size limit was described by hardware manufacturer Bitmain in June 2017 as a "contingency plan" should the Bitcoin community decide to fork; the first implementation of the software was proposed under the name Bitcoin ABC at a conference that month. In July 2017, the Bitcoin Cash name was proposed by mining pool ViaBTC.
Because Bitcoin isn’t controlled by a single company, there is no help if you make an error. For example, if you forget the “password” to your Bitcoin wallet, there is no company to contact to reset your password. You might be asking “But what happens if I accidentally send my Bitcoins to the wrong place?” well, the simple answer is that your Bitcoins will be gone forever.  

This development could mean any number of things for the future of cryptocurrency. The situation is very fluid, and market valuations are both constantly calibrating and volatile. It’s going to be difficult to get a clear picture until bitcoin cash has been running for a while (or fails), the impact of bitcoin's segregated witness technology is assessed, and the size of Bitcoin's blocks are doubled.
Bitcoin exchanges are companies that create a live market for buying and selling bitcoin. Customers will deposit bitcoin or fiat currency into their accounts and then place different order types that are recorded on an order book managed by the exchange. Some exchange offer simple limit orders, while others offer advanced order types such as stop loss orders and margin trading.
Before you buy Bitcoin, you need to download a Bitcoin wallet by going to a site like Blockchain.info, or to a mobile app such as Bitcoin Wallet for Android or Blockchain Bitcoin Wallet for iOS, and filling out an online form with basic details. This shouldn't take more than two minutes. (Related reading, see: Basics For Buying And Investing In Bitcoin)
You’d be in good company in that case, anyway. Jack Bogle’s bitcoin investment advice is pretty simple, and blunt: You should avoid Bitcoin speculation “like the plague.” And this is coming from the guy who founded Vanguard, so he knows a thing or two about investments. The other risk to keep in mind if you plan to invest in bitcoin, aside from the overall volatility of the cryptocurrency, is of a cyber attack. Hackers descended on digital currency exchange Bitfinex on Tuesday, less than a week after cybercrooks made off with $70 million in a separate heist.

An outstanding introduction into the Bit coin world, testimonials from successful investors as well as details of the possible pitfalls. A must read to get a good read to get started. Bit coin investing and the quick history give even the novice the tools to get started. Even if you choose not to invest this book allows you to at least understand this new world.
Nvidia (NVDA) , a holding in Jim Cramer's Action Alerts PLUS Charitable Trust Portfolio, and AMD (AMD) are companies that make several types of technology; AMD makes processors for desktop and laptop computers, while Nvidia's products range from automotive use to cloud servers. Where the two most successfully intersect, though, are their graphics processing units. Even in the age of ASIC miners, a strong GPU has proven to be a competitive (and much more affordable) way to mine bitcoins.

But here, more than anywhere else, is where you need to proceed with caution. Bitcoin is already incredibly risky, imagine what risks smaller and lesser-known crypto brings. Rounding out a portfolio with other cryptocurrencies may be able to help you evaluate the state and perhaps the future of that market, but many of them can quickly prove to be a flash in the pan. The sudden rise of initial coin offerings -- a method of crowdfunding new cryptocurrencies in a way that avoids venture capital entirely -- has many people excited for the future, but also has many wondering if it's going to create an even more dangerous bitcoin bubble.
Improving cryptocurrency as a transaction medium will depend on maintaining the high level of security that bitcoin has always ensured, while also improving transaction speeds. Bitcoin will continue to be highly secure, but how much its transaction speeds will improve is unclear. Bitcoin cash, once its difficulty has adjusted, could have transactions processing in two minutes and 30 seconds. The security of the Bitcoin cash blockchain, though, is unclear.

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.
The bitcoin-ml mailing list is a good venue for making proposals for changes that require coordination across development teams. Workgroups have been set up to assist developers to coordinate and seek peer-review. For those wishing to implement changes to the Bitcoin Cash protocol, it is recommended to seek early peer-review and engage collaboratively with other developers through the workgroups.

Hardware wallets are the option I recommend for storing your Bitcoin. They allow you to store your Bitcoins offline on a small piece of hardware. You plug the hardware wallet into your computer (with a USB) and transfer your Bitcoins on to it. This allows you to store your Bitcoin offline so that they can’t be hacked. When wondering how to invest in Bitcoin, I would definitelly go for the most secure wallet.
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.

Bitcoin is often touted as an electronic currency that will change the world, but it is also a highly volatile type of financial asset. In fact, many governments don't recognize it as a currency at all. In spite of the many merchants now excepting bitcoin, a lot of the activity surrounding bitcoin comes from traders hoping to make money on fluctuations in its value.
To achieve this, Bitcoin SV makes a few changes relative to Bitcoin ABC right now. First, it rejects CTOR, as nChain believes the potential benefits are insufficiently proven and the risks are too high. Second, it increases the default block size limit to 128 megabytes (versus Bitcoin ABC’s 32 megabytes). And third, it reinstalls several old OP codes (with names as OP_MUL, OP_LSHIFT, OP_RSHIFT and OP_INVERT). It also removes the size limit on scripts.
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.
