here is the liist of top 7 best crypto currencies of 2018 these rankings are based upon the marketcap of each cryptocurrency.
bitcoin It is the first decentralized digital currency with the total market cap of 140 billion dollar as of may 2018
back in 2017 price of 1 bitcoin went to 20,000 us dollars now its price is 8000$
bitcoin's supply is limited to 21 million coins and 17 million coins are already mined.
Research by the University of Cambridge estimates that in 2017, there were 2.9 to 5.8 million unique users using a cryptocurrency wallet, most of them using bitcoin.
Ethereum is an open-source, public, blockchain with th total market cap of 68 billion dollars.
The system went live on 30 July 2015, with 11.9 million coins "premined" for the crowdsale.This accounts for about 13 percent of the total circulating supply.
In 2016 Ethereum was split into two separate blockchains – the new separate version became Ethereum (ETH), and the original continued as Ethereum Classic.
in 2017 the value of the Ethereum currency grew over 13,000 percent and hit an all-time high of $1,417 .
Ripple is a real-time gross settlement system (RTGS), currency exchange and remittance network created by the Ripple company
Ripple has been increasingly adopted by banks and payment networks as settlement infrastructure technology,
As of the first week of March 2018, XRP is the third largest coin with the marke cap of 68 billion dollars.
Ripple allows for cross-border payments for retail customers, corporations, and other banks,
IN August 2017,he developers implemented a change to the bitcoin code called hard fork which gave birth to Bitcoin Cash.
the market cap of bitcoin cash is 20 billion dollars. it has the same limit as bitcoin of 21 million coins.
The first implementation of the Bitcoin Cash protocol called Bitcoin ABC was revealed by Amaury at the Future of Bitcoin conference in Arnhem, Netherlands.
On May 15, 2018 the protocol was upgraded via a planned hard fork to increase the block size limit from 8 to 32 Megabytes.
EOS is a cryptocurrency token and blockchain that operate as a smart contract platform for the deployment of decentralized applications and decentralized autonomous corporation.
EOS aims to become a decentralized operating system supporting industrial-scale applications, with claims to eliminate transaction fees and also conduct millions of transactions per second.
as of may 2018 the market cap of EOS token is 11 billion dollars.
The aim of the platform is to provide decentralized application hosting, smart contract capability and decentralized storage enterprise solutions that solve the scalability issues of blockchains like Bitcoin and Ethereum,
Litecoin is a peer-to-peer cryptocurrency and open source software project with the market cap of 7 billion dollars.
Litecoin was released via an open-source client on GitHub on October 7, 2011 by Charlie Lee, a former Google employee.
Creation and transfer of coins is based on an open source cryptographic protocol and is not managed by any central authority.
During the month of November 2013, the aggregate value of Litecoin experienced massive growth which included a 100% leap within 24 hours.
Cardano is a platform that runs the blockchain for the Ada cryptocurrency Daedalus is currently the only cryptocurrency wallet that holds Ada and allows transfers to other wallet addresses.
Cardano (ADA) was released on September 29, 2017 under the 'Byron' bootstrap phase with the official launch in Japan
Cardano sold 26 billion tokens (called 'vouchers') in an initial crowdsale, with an addtional 20% of that total (~5.1 Billion tokens) . the total supply of ADA is 45 billion coins.
Coins are mined and decisions are made via a proof-of-stake algorithm called Ouroboros instead of a proof-of-work system
The miners are interested in finding a nonce which will create a hash with certain characteristics. Lastly, they have to find a random value that they included in the header, which makes the computed hash over that header a value below a particular target. In other words, they do not have to agree to change the protocol. Though there are a few gold diggers attempting to fill their pockets and certain projects that aren`t viable and shouldn`t be encouraged in any way. For users running a complete node, it is a fairly painless procedure to upgrade the software to the newest version. The process of locating a new block to extend the blockchain is known as mining. Proof-of-Work systems utilize cryptographic hashing algorithms to create the action of mining a block a complicated computation. Our software is totally incompatible with altcoins. Changes and modifications to how that it works need to be approved by consensus and every CPU gets a vote. To start with, it`s essential to realize that hardware wallet users control entirely their private keys. Whether you`re bullish or bearish on Bitcoin Gold, you ought not lose your coins as a result of careless mistakes! On the 1 hand, it may result in making a coin that solves all the pending issues. There`s no currency or digital asset named Bitcoin Core. Bitcoin Cash increases the range of transactions that may be processed per block. You could send any quantity of money, any place in the Earth, almost at no cost. You`ve made some great money already on the market, but you want more. For a wealthy individual, BTC`s price premium may be viewed as a plus. For someone without lots of money, BCH`s low price may look like a great deal for Bitcoin. If you have some concerns about the worth of Bitcoin after all forks, you need to be ready for a drop. The distinction is that not all of these suffer the chain split. The primary problem is Bitcoin imposes a hard limit on the magnitude of a block, the location where transaction information becomes stored. The end result is many straightforward wallets, called SPV wallets and very commonly found on your phone, will be quite confused about which chain is Bitcoin. In Bitcoin, the most important reason is known as the network effect.
