Advice from 2015: As a rule of thumb, don’t acquire any volatile assets you can’t afford to lose. This is a valuable guideline for investments in general. It’s important to look at the history of the value of Bitcoin. In late 2013 and early 2014, Bitcoin gained considerable Media attention, and the price of all coins inflated wildly and unreasonably. Since then most coins have leveled out at about double their pre-2014 value, but there is still plenty of room for the price to go down. History has shown us that there is plenty of room to go up as well. $1,000 Bitcoins? It happened once; it could happen again.
In general most people won’t see a big return for a myriad of reasons (many having to due with human emotion and skill levels vs. the volatility in the crypto space). However, if you pick solid coins and invest or trade using a solid strategy, you do have a solid chance to see decent returns over time historically speaking (in other words, had you invested or traded wisely in the past, you would have had opportunities to see returns thus far).

NEM — Unlike most other cryptocurrencies that utilize a Proof of Work algorithm, it uses Proof of Importance, which requires users to already possess certain amounts of coins in order to be able to get new ones. It encourages users to spend their funds and tracks the transactions to determine how important a particular user is to the overall NEM network.

Unlike ordinary money, cryptocurrency prices are highly volatile, so the rate may fluctuate. It may happen that the altcoin exchange rate which you see before the transaction is different (high or low) after transaction gets completed. In that case, the exchanged digital currency quantity which you receive may differ from what you see during the comparison.

One of the newest digital currencies to make our list is EOS. Launched in June of 2018, EOS was created by cryptocurrency pioneer Dan Larimer. Before his work on EOS, Larimer founded the digital currency exchange Bitshares as well as the blockchain-based social media platform Steemit. Like other cryptocurrencies on this list, EOS is designed after ethereum, so it offers a platform on which developers can build decentralized applications. EOS is notable for many other reasons, though. First, its initial coin offering was one of the longest and most profitable in history, raking in a record $4 billion or so in investor funds through crowdsourcing efforts lasting a year. EOS offers a delegated proof-of-stake mechanism which it hopes to be able to offer scalability beyond its competitors. EOS consists of EOS.IO, similar to the operating system of a computer and acting as the blockchain network for the digital currency, as well as EOS coins. EOS is also revolutionary because of its lack of a mining mechanism to produce coins.

Decentralized cryptocurrency is produced by the entire cryptocurrency system collectively, at a rate which is defined when the system is created and which is publicly known. In centralized banking and economic systems such as the Federal Reserve System, corporate boards or governments control the supply of currency by printing units of fiat money or demanding additions to digital banking ledgers. In case of decentralized cryptocurrency, companies or governments cannot produce new units, and have not so far provided backing for other firms, banks or corporate entities which hold asset value measured in it. The underlying technical system upon which decentralized cryptocurrencies are based was created by the group or individual known as Satoshi Nakamoto.[23]
