In 2009 Satoshi Nakamoto had found a way to build a decentralized coin and cash system without a central unit. From this Bitcoin was introduced to the world as the first digital currency of its kind. The “blockchain” is the master ledger that records and stores all the transactions and mining activity, trades, and purchases. At the same time, it requires validation of ownership. Technically a transaction is not finalized until it is added to the blockchain which usually takes a few minutes and is irreversible. During the time between transactions, the units are not available for usage by either side, which prevents double spending, fraud, and duplication. Each user has a “wallet” with specific information that confirms them as the owners of any specific cryptocurrency. Each user’s wallet allows them to send and receive coins and acts as a personal ledger of transactions. These wallets are built to be secure however additional measures and passwords need to be considered to keep them secure. The wallets can be stored on a cloud or an internal hard drive. The “Miners” act as the “record keepers” for the cryptocurrency communities. Through technical methods they create new coins and verify the blockchains.
EOS is also the first blockchain with a constitution. There are governing principles that every stakeholder agrees on, and the set of rules is attached to every block that is mined. EOS will have the capability to process millions of transactions each second using horizontal scaling. This is much different from Bitcoin and Ethereum. The current model also allows for 5 percent inflation, which can be used to further develop the network. In addition, EOS does not require users to pay for each transaction, which will help fuel adoption.

Dogecoin: Dogecoin (like the “Doge” internet meme about a dog and misspelling) had the 7th highest Market cap as of June 2015. In 2017 it was still a contender although it was more of one early in 2017. Individual coins aren’t worth as much as other coins on the list, but it’s value and popularity have remained relatively steady despite notable highs and lows. Dogecoin uses the same essential technology as Bitcoin with a few important technical distinctions. Like the failed Coinye West, Dogecoin was just in it for the lolz (i.e., it was created as a joke), but unlike Coinye, Dogecoin became inexplicably popular. Why do we suggest a joke coin? Because it’s a popular coin and today the only funny part about it is the name (and it’s mascot and backstory). It’s a lot like Litecoin — a fairly priced coin with some degree consumer confidence. Dogecoin has, one might argue, turned their comedic origins into an excuse to make their coin “fun and friendly,” which was a smart long-term move. It’s also one of the only major cryptocurrencies with a .com Top-Level Domain name and is one of the few that attempts to reach an audience outside of techies and cryptography nerds. As of September 2017, Dogecoin had taken a beating in value. One could argue that its roots as a joke coin weren’t as great a long-term strategy as it had once seemed (although one could argue the volatility it has seen is just business as usual in the cryptocurrency space.)
What is cryptocurrency is a common question amongst new people who first hear about bitcoin or other cryptocurrencies. Cryptocurrencies are defined as digital assets used for medium of exchange with strong cryptography securing transactions, controlling possible creation of additional tokens or coins and verifying asset transfers. What is cryptocurrency backed by is another common question from people who are looking to get into crypto, and for that the answer is not so simple. Some of the cryptocurrencies are not backed by anything, and some of them are backed by physical assets.
A beginner might prefer to trade cryptocurrency stocks on the stock market. For example, GBTC is a trust that owns Bitcoin and sells shares of it. Trading GBTC avoids you having to trade cryptocurrency directly, but still allows you exposure to Bitcoin. Beyond GBTC (and the Ethereum Classic version ETCG), your options are very limited for crypto stocks. Be aware that GBTC trades at a premium (meaning bitcoins are cheaper than buying shares of the GBTC trust), which isn’t ideal. Also, cryptocurrency trading is a 24-hour market, where the traditional stock market is not. Learn more about the GBTC Bitcoin Trust and the related pros and cons before you invest.
They’re committed to safe and secure trades, because at the end of the day, you’re trusting your money with them. They understand that, and they take that very seriously. Their system is 100% proprietary, has been stress tested and DDoS tested, and they have never lost a single coin. They also maintain a ledger themselves in the interest of ensuring that they know where every coin – whether Canadian or ethereum – is at all times.
The term altcoin has various similar definitions. Stephanie Yang of The Wall Street Journal defined altcoins as "alternative digital currencies,"[20] while Paul Vigna, also of The Wall Street Journal, described altcoins as alternative versions of bitcoin.[21] Aaron Hankins of the MarketWatch refers to any cryptocurrencies other than bitcoin as altcoins.[22]
