Like all other markets like shares, stocks, and currencies, cryptocurrencies also have a huge space in the trading market era. Bitcoin is the first cryptocurrency or digital currency created by a group or individual name called Satoshi Nakamoto. But initially, people have no hope in this kind of format currency totally new and so technically.
People started to think this is created to scam huge funds from people. Even though it started with cents in dollars. But the technology behind these coins was blockchain. It is totally decentralized. When most of all currencies and commodities are centralized. So people always have a big scare on the centralized model of currency or shares which is mostly owned by the government. So whatever people wanna do it will make an account and it is limited.
With these disadvantages, people’s started to think on decentralized currencies like bitcoin which was the only cryptocurrency at that time. So the cryptocurrencies era started and move on. So people to exchange their fiat currencies with bitcoin. So whoever owns bitcoins can send to friends or whoever in the blockchain technology within a minute. No need to wait for the centralized authority to accept this.
So how to buy the bitcoin? for this the answer the cryptocurrency exchanges created by the common people or organizations. So people whoever want to buy bitcoin they can buy with the fiat currencies in the crypto exchanges.
Now we are in 2020, the world totally changed with the new era with more than 3000 cryptocurrencies around the world. Even though all coins are called cryptocurrency but except bitcoin, every coin is called altcoins or tokens.
After bitcoin, some leading cryptocurrencies are ethereum, tether, ripple, bitcoin cash, etc are in the market now.
As mentioned in the Wikipedia the blockchain
The validity of each cryptocurrency’s coins is provided by a blockchain. A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block typically contains a hash pointer as a link to a previous block, a timestamp and transaction data. By design, blockchains are inherently resistant to modification of the data. It is “an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way”. For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority.
Blockchains are secure by design and are an example of a distributed computing system with high Byzantine fault tolerance. Decentralized consensus has therefore been achieved with a blockchain. Blockchains solve the double-spending problem without the need of a trusted authority or central server, assuming no 51% attack (that has worked against several cryptocurrencies).
The cryptocurrency market is always volatile. There are most of the website’s are providing real cryptocurrency data. Some of the best cryptocurrency market analysis platforms are Coinmarketcap, Coinlib, Tokenncoin and crypto compare, etc.
