Pro Tip:If you want to invest, but aren’t keen on using your own funds, consider utilizing accrued interest on a savings account to invest. Compare savings accounts and their interest rates. If you put a lot of money into savings every year, you could fund a sizable investment with just the money the bank pays you in interest. It eliminates your personal risk and maximizes your chances of a return.
This fast has brought so much attention to altcoins, and it’s coming to be that a coin will go up in value simply because it’s on the market. So many new investors want to get in on the ground level, so they’ll pump impressive funds into initial coin offerings (ICOs) with the hopes of literally getting rich overnight. For many investors, this actually comes true. A coin will take off after releasing to the public and early investors are rewarded greatly.
Merchants must be wary of their customers, hassling them for more information than they would otherwise need. A certain percentage of fraud is accepted as unavoidable. These costs and payment uncertainties can be avoided in person by using physical currency, but no mechanism exists to make payments over a communications channel without a trusted party.

Indeed, the only thing a 51% attacker could really accomplish is destroying collective faith in bitcoin. They couldn’t somehow steal and gain all the value of bitcoins for itself. The attacker wouldn’t be able to generate new bitcoins on demand arbitrarily, and would still have to mine for them. They also would have no control over taking bitcoins created in the past that didn’t belong to them. The only thing they could do, really, is repeatedly spend bitcoin they already owned again and again, but even this is limited in its value, because ‘honest’ miner nodes would never accept these fraudulent payments.
With this in mind, bitcoin can arguably be seen as the purest form of money, as its value is entirely predicated on trust in it, and nothing else. It can arguably also be seen as the most trustworthy of currencies, as it was bespoke made by intentional design to exhibit all the best elements of historically trustworthy currencies (e.g. gold), as well as to introduce for the first time a number of characteristics that make it even better than all previously extant currencies.
With cryptocurrencies, diversification simply doesn't exist. We'd like to think it does, as there are more than 1,600 investable virtual currencies, each with their own plan of action and often proprietary blockchain -- the underlying digital and decentralized ledger responsible for recording all transactions without the need for a bank. But the fact of the matter is that most cryptocurrencies tend to move in tandem with bitcoin, the largest digital currency of them all. This association almost always negates the impact of diversification.
Bitcoin is a decentralized currency that uses peer-to-peer technology, which enables all functions such as currency issuance, transaction processing and verification to be carried out collectively by the network. While this decentralization renders Bitcoin free from government manipulation or interference, the flipside is that there is no central authority to ensure that things run smoothly or to back the value of a Bitcoin. Bitcoins are created digitally through a “mining” process that requires powerful computers to solve complex algorithms and crunch numbers. They are currently created at the rate of 25 Bitcoins every 10 minutes and will be capped at 21 million, a level that is expected to be reached in 2140.

IBM (IBM) has developed blockchain technology that they are using with a large variety of partners in a large variety of industries. One example is their partnership with food retailers, most notably Walmart, to help quickly, efficiently, and securely track the supply chain to help ensure ideal food safety. They have also partnered with Maersk to work on a blockchain platform for global trade.
The Bank for International Settlements, the central banker for global central banks, has warned that cryptocurrencies in the future could become a "threat to financial stability" if regulators aren't vigilant. U.S. regulators appear to be playing catch-up. As of Feb. 6, the cryptocurrency working group put together by Treasury Secretary Steven Mnuchin had held a single meeting.

Over the past six months, the cryptocurrency crash has brought out the skeptics. In fact, the ongoing “Crypto Winter” is a healthy cleansing of the ecosystem because the correction is effectively separating long-term value creators from short-term day traders. All in all, we believe that a “Crypto Spring” will arrive. And, institutional capital, a.k.a. the sticky, smart money, could possibly usher in this new season.
