The first cryptocurrency to capture the public imagination was Bitcoin, which was launched in 2009 by an individual or group known under the pseudonym, Satoshi Nakamoto. As of February 2019, there were over 17.53 million bitcoins in circulation with a total market value of around $63 billion (although the market price of bitcoin can fluctuate quite a bit). Bitcoin's success has spawned a number of competing cryptocurrencies, known as "altcoins" such as Litecoin, Namecoin and Peercoin, as well as Ethereum, EOS, and Cardano. Today, there are literally thousands of cryptocurrencies in existence, with an aggregate market value of over $120 billion (Bitcoin currently represents more than 50% of the total value).
Ripple is a real-time global settlement network that offers instant, certain and low-cost international payments. Launched in 2012, ripple “enables banks to settle cross-border payments in real time, with end-to-end transparency, and at lower costs.” Ripple’s consensus ledger (its method of conformation) is unique in that it doesn’t require mining. In this way, ripple sets itself apart from bitcoin and many other altcoins. Since Ripple’s structure doesn't require mining, it reduces the usage of computing power, and minimizes network latency. Ripple believes that “distributing value is a powerful way to incentivize certain behaviors” and thus currently plans to distribute XRP primarily “through business development deals, incentives to liquidity providers who offer tighter spreads for payments, and selling XRP to institutional buyers interested in investing in XRP.” So far, ripple has seen success with this model; it remains one of the most enticing digital currencies among traditional financial institutions looking for ways to revolutionize cross-border payments.
Just figure out, what coin do you want to buy and seek for a stable wallet version. As a rule, each coin has its official wallet client. Note that each wallet has its unique address or a tag with a private key that is required to restore your wallet if lost. CoinSwitch never asks your private keys. Store them in a safe place and never show anyone. Once private keys are stolen, your cryptocurrency wallet with all the coins will be lost forever.
Charles Hoskinson, one of the co-founders of ethereum, launched cardano in September of 2017. For supporters of this digital currency, ADA offers all of the benefits of ethereum, as well as many others. Cardano offers a platform for Dapps and smart contracts, like ethereum before it. Beyond that, ADA aims to solve some of the most pressing problems plaguing cryptocurrencies everywhere, including interoperability and scalability. Cardano also hopes to tackle issues related to international payments, which are typically both timely and expensive. Thanks to its focus on this area, ADA was able to take international payment processing times from days down to just seconds. As of February 9, 2019, cardano had a market cap of $1.16 billion and a per token value of $0.041.
For takers, fees range from 0.10 to 0.25%. There are no fees for withdrawals beyond the transaction fee required by the network. One of the unique tools on the Poloniex platform is the chat box which is constantly filled with user help and just about everything. Any user can write almost anything but inappropriate comments are eventually deleted by moderators. It can sometimes be hard to distinguish the good advice from the bad, but the Chatbox is a great tool that will keep you engaged.
NOTE: Once you have Coinbase down, try moving onto Coinbase Pro. It’s, in overly simple terms, like a better version of Coinbase with lower fees. Coinbase operates both platforms, and both use the same logins. Coinbase Pro is the preferred exchange of many Bitcoin traders in the U.S. It caters to both pros and novices. After you master that, then consider exchanges like Bittrex and Binance.
A lot of concerns have been raised regarding cryptocurrencies’ decentralized nature and their ability to be used almost completely anonymously. The authorities all over the world are worried about the cryptocurrencies’ appeal to the traders of illegal goods and services. Moreover, they are worried about their use in money laundering and tax evasion schemes.
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.

Ethereum: an open-source cryptocurrency launched in 2015 and proposed by Vitalik Buterin, Garvin Wood, and Joseph Lubin. It is based on the blockchain model whose main objective is the decentralization of the market. In 2016 there was a fork from which the Classic Ethereum emerged. Currently and since its inception, Ethereum ranks second in tems of the market capitalization.
A cryptocurrency (or crypto currency) is a digital asset designed to work as a medium of exchange that uses strong cryptography to secure financial transactions, control the creation of additional units, and verify the transfer of assets.[1][2][3] Cryptocurrencies use decentralized control as opposed to centralized digital currency and central banking systems.[4]
