Second, there are no fundamental metrics for investors to examine, making a comparison between virtual currencies both difficult and arbitrary. At best, investors can look to project partnerships and processing speed as a few noteworthy comparisons, but that should be hardly enough to decipher whether one cryptocurrency will outperform another over the long run.

Psychologically, if it’s helpful, I think it may be fine to sell off some small portion of your upside if you do realize upside over time, in order to recoup your initially invested principal. I don’t think that this is necessarily the most optimal actual move to make, but do think it likely makes a huge difference psychologically, such that it makes it far easier for you to hold your remaining investment with sangfroid in the case that it ends up cratering sometime in the future.

While it is enticing to attribute the underwhelming trading volumes to the decline in the underlying assets’ valuation, some observers point out that the two are actually tied in a kind of an egg-and-chicken cycle, mutually influencing each other. As early as in January, when a multitude of versions explaining the crash of Bitcoin price began to emerge in media space, one of the less-visible yet sound considerations was that futures trading had opened the crypto markets to bear investors.
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.

The latter is very important, as situations where investors lose their funds due to hacks and security breaches happen quite often. This is why traders try to pick exchanges which can offer insurance (like Coinbase does) or have some sort of reserve fund to cover expenses if something happens. For example, Bithumb exchange which was recently hacked, promised that it would fully compensate users out of its fund of $450 million.
Guy Hirsch, the US Managing Director of the trading platform eToro, recently shared his thoughts on the future of cryptocurrency index funds and ETFs, as well as the different aspects of institutional investment in cryptocurrency in an exclusive interview with ETF Trends. Hirsch told ETF Trends that institutional investors understand blockchain’s potential, adding the U.S. [...]

Do note that this will put your portfolio out of balance. But it’s prudent to do this as a measure of risk mitigation whenever your portfolio has been doing incredibly well. The market won’t go up forever, and you can rest assured that there will always be another correction. By taking profits in Bitcoin, you partly secure your profits while at the same time staying in the game lest you miss out on another leg of a bull run.

If somehow, you’ve only heard of one cryptocurrency, it’s probably Bitcoin. It is the biggest cryptocurrency — it currently has a 40%i share in the total cryptocurrency market cap! It is the oldest cryptocurrency and it still dominates in the market. So, if Bitcoin continues to increase like it did in 2017, then investing in Bitcoin might be a good idea for 2018.
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.
These are cryptocurrencies bound to blockchains that allow for the creation of applications on them, such as Ethereum, NEO, Cardano, Lisk, VeChainThor, and many more. The underlying platforms of these coins create an actual need – and thus a demand – for the coins, as they are needed to make use of the applications and buy into ICOs. In my opinion, these coins are currently the safest and have the largest growth potential, as the blockchains they are built on have the capacity to become the foundation of the decentralized world.

Because we believe the cryptocurrency market to be quite volatile, having a defensive portfolio to counter that volatility is good. 50% of my portfolio is low risk (compared to crypto risk management), which means that it will be holding Bitcoin for the long term, because it has a lot of longevity. It is the oldest cryptocurrency in the space, and is the first coin that newcomers are likely to invest in because of the exposure it regularly gets in the press.

Some bitcoin exchanges allow account holders to short — bet that bitcoin will fall in value — but the ordinary investor cannot do this as easily with bitcoin as with stocks or exchange-traded funds. Shorting is easy on the futures markets, however, as the trader simply buys a contract to sell a block of bitcoin at today's price sometime in the future. If it works out the price will fall and the bet will pay the difference.
When too many people pump and dump these coins over and over, they lose their power. For example, if a coin goes up and down so much, then fewer investors are likely to hop on board once it starts to go up again. They might think, “This coin goes up, but it always comes down. I’m not going to risk it by investing.” This is actually harmful to a coin when it skyrockets and crashes, and this is why you should be wary in 2018 where you put your money.
Even though other transaction coins will definitely grow in value in the next few years, I think that Bitcoin will remain the dominant currency in this segment. While others may be faster, less centralized, or more private, Bitcoin’s incredible first mover advantage and allowance for upgrades makes me continue to place my faith in the reigning monarch of cryptocurrencies.
This is when I first saw the light, and realized that investing in altcoins that I didn’t really believe in, and that didn’t really have any truly compelling reasons they would ever overtake bitcoin or deserve any level of market share, was an incredibly foolish move. It was certainly true that these altcoins did often gain on bitcoin and appreciated far more rapidly in many cases while the bubble held strong, but the moment it began to collapse, the altcoins were the first to go, and often fell all the way to zero.
