Everything has a great history behind it. It was new for me that it was introduced so many years ago.
Let me tell you the history of electronic money
In 1983, David Chaum introduced the idea of digital currency. He founded digicash, an electronic cash company in 1989, in Amsterdam to flourish the ideas in his research.The company filed for bankruptcy in 1998.
e-gold was the first widely used Internet money, introduced in 1996, and was used by many million people before the US Government shut it down in 2008. e-gold has been referenced as “digital currency” by US officials.In 1997, Coca-Cola also offered buying from vending machines using digital payments. PayPal launched its USD-denominated service in 1998. bit coin was
launched in 2009, which marked the start of digital currencies with no central server. Also known as cryptocurrencies, digital currencies were proved reluctant to attempt by the government to regulate them, because there was no central organization or person associated with them,this resistance is still continuing.
Another known digital currency service was Liberty Reserve, founded in 2006,it lets people convert dollars or euros to Liberty Reserve Dollars or Euros, and exchange them freely with one currency to another at a rate of 1% fee. Q coins or QQ coins, were used as a type of digital currency on Tencent QQ’s messaging platform and emerged in early 2005.
Many developed and super power nations have widely accepted digital money as it has started replacing their own physical currency.
Nowadays bit coin is the most famous, widely used and accepted form of electronic money.
More than 67000 digital currencies are introduced in the following years.
How to buy digital currency
You need a “wallet,” an online app that can hold your currency. You create an account on an exchange, and then you can transfer real money to buy cryptocurrencies such as bit coin or Cardanol.
Coin base is a popular cryptocurrency trading exchange where you can create both a wallet and buy and sell bit coin and other cryptocurrencies. Also, a growing number of online brokers and other traders offer digital currencies or cryptocurrencies for fast exchange as there is no bank or any other server involved between the two parties.
It is exchanged through smart phones credit cards or its own online exchange sites.
Top five types of digital money.


Bitcoin is a cryptocurrency invented in 2008 by Satoshi Nakamoto. Exchange widely without any bank or organization and transactions are recorded in blockchain , a ledger for keeping records. Bitcoins are created for a process known as mining. They can be exchanged for other currencies and products. In 2017, Research produced by the University of Cambridge estimated that, there were 2.9 to 5.8 million unique users using a cryptocurrency wallet, most of them using bit coin. People all around the world choose to participate in the digital currency for a number of reasons: ideas such as decentralization and libertarianism, convenience, using the currency as an investment and preventing themselves from bogus transactions. Increased use has led to a desire among governments for regulation of digital currency to facilitate legal use in trade and for other reasons.
Bitcoin has been criticized for its use in illegal transactions, the large amount of electricity (and thus carbon footprint) used by mining, price volatility, and thefts from exchanges. Highly used
cryptocurrency by traders and investors nowadays.
Bitcoin is represented as an elliptic curve called secp256k1.The unit used for the bit coin system is a bitcoin. Symbols that represent bitcoin are BTC.
Wallet holds the information necessary to transact bit coin. A wallet is more correctly defined as something that “stores the digital credits for your bit coin holdings” and allows easy access to them.
There are several modes which wallets can perform work.
Full clients can verify transactions directly by downloading a full copy of the blockchain .They are the most secure and reliable way of using the network, as interruption of any external party is not needed.
Lightweight clients(on the other hand), have to consult full nodes to send and receive transactions without needing a copy of the entire blockchain and this idea is not valid one and can lead to fake transactions and trades.
Physical wallets store the users achievements to spend bitcoins offline and can be as simple as a paper printout. A paper wallet is created with a keypair made on a computer with no internet connection; the key is printed onto the paper and then deleted from the computer. The paper wallet can then be stored in a safe physical location for later use. Bitcoins used by this method are called cold storage .
Coming towards the rates of btc, so the current market capacity of bit coin is 1,071,811,603,782 and price is $57,340.00.
Volume is $71,113,113,206 circulating supply rate is 18,686,125 having a change of 4.5% in the last 24 hours.


The second most widely used cryptocurrency is Ethereum. This was first discovered by Vitali Butlerin. They are mostly used for storage, unlike bitcoins but are also being used for transactions.
Standard tokens for Ethereum are ETC-20 tokens on the blockchain which keeps the record of transfer of tokens and their amount stored or transacted.
Ether (ETH) is the cryptocurrency generated by the Ethereum inventors for miners for adding blocks to the blockchain. Ether provides greater facility for the miners to easily exchange and transact their credentials. The block reward and the transaction fees provide miners the facility to keep the blockchain growing.
Each Ethereum account has an ETH balance and ETH can be exchanged to any other account. The smallest subunit of ETH is called a Wei and is equal to 10-18 ETH.
Ether is represented on exchanges as the symbol ETH. The Greek uppercase Xi (Ξ) symbol is used for its currency symbol.
There are two types of accounts on Ethereum: user accounts and contracts.
Both types have an ETH balance, can send ETH to other accounts, make transactions without involving any other source.
Ethereum addresses are composed of the prefix “0x”, a common represented for hexadecimal, written with 20 bytes of the Keccak-256 hash. In hexadecimal two digits equals a byte, so addresses contain 40 hexadecimal digits, e.g. 0xb794f5ea0ba39494ce839613fffba74279579268.
Sources are underway for making major upgrade to Ethereum known as Ethereum 2.0
or Eth2.The main purpose of the upgrade is to increase the transactions throughout the Ethereum platform from the current fifteen transactions per second to up to tens of thousands of transactions per second.
Total supply of Ethereum is 115.53M with volatility of 0.73. Average rate is about
$2,282.78 with rise and fall every 24 hours.
Still many brokers or investors feel risk in using ethereum because of its faulty wallets and blockchain deformities.


Binance Coin
Bnb is the symbol used for binance coin. Over the past 3 years, binance coin currency has raised to heights leading to many million transactions per second. The future growth of this cryptocurrency in the near future is very high but still is has some issues with its wallets and record chain.
Binance coin unlike bit coin and Ethereum is created by a company so still some investors find it reluctant to invest in this cryptocurrency.
Otherwise binance coins can be shared by credit cards, smartphones, wallet apps and other sources as well.
The today price of a binance coin is $480.42 with a change of 5.6% rise and fall in 24 hours. the circulating supply of binance coin is 115,533,921.


2012, J.R. Willett published the idea of tether currency through a magazine. The exchange company of tether was BITFINEX. The Tether was easily exchanged by bitfinex with other countries. It raised to many heights in the years
even replacing the bitcoin in the previous years. The thing which caused its fall during 2018 was the controversy associated with it. Bitfinx claimed that tether token was backed by the dollar all theri acclaim proved wrong many people claimed that it was illegally manipulating the value of bitcoin
In 2019, again tether surpassed the volume and market index of bitcoin becoming again a popular digital currency.
Symbol used for the tether ticket is USDT.
The market price is $0.99 having volume $167,379,660,802
The problem that it’s still on number four, is the controversy behind it ,if in the upcoming years their claim proved wrong, tether would see a huge drop.


Cardano is found by some users appealing because its fewer expanded platforms can be easily accessible and exchanged as compared to other rival cryptocurrencies.
But many investors or buyers are hesitant to invest in cardano as its small expansion and platforms.
Ticket symbol or cardano is called ADA.
Launched by CHARLES HOCHINKSON in late 2017 through a published paper.
In every means Cardano quite resembles bitcoin and Ethereum that can be exchanged, transacted and stored.
Its developers also claim that cardono is the most powerful digital currency currently, as it covers almost the digital areas required by any broker,investor,credit card user,transacter and trader.
Price in the market is $1.20 with variation of approximately 2.4% every 24 hours.
Having a volume rate of $5,064,967,458 with market capacity 38,067,556,316 and circulating supply of 32,041,754,672.
