A cryptocurrency is a digital asset designed to work as a medium of exchange that uses cryptography to secure its transactions, to control the creation of additional units, and to verify the transfer of assets.
Bitcoin is a cryptocurrency and worldwide payment system. It is the first decentralised digital currency, as the system works without a central bank or single administrator.
You should never expect to get rich with Bitcoin or any emerging technology. It is always important to be wary of anything that sounds too good to be true or disobeys basic economic rules. Bitcoin is a growing space of innovation and there are business opportunities that also include risks. There is no guarantee that Bitcoin will continue to grow even though it has developed at a very fast rate so far. Investing time and resources on anything related to Bitcoin requires entrepreneurship. There are various ways to make money with Bitcoin such as mining, speculation or running new businesses. All of these methods are competitive and there is no guarantee of profit. It is up to each individual to make a proper evaluation of the costs and the risks involved in any such project.
Bitcoins can be sold locally using LocalBitcoins, on Bitcoin brokerages / exchanges, using two-way Bitcoin Teller Machines (BTM’s) or you can pay for a good or service with them. Bitcoins can be sold to just about anyone as long as they have a Bitcoin address, and can be sold for any fiat currency in the world or traded for a physical good. Feel free to check out our recommended list of exchanges and brokerage services to sell your bitcoins online.
A blockchain is the technology on which cryptocurrency is based. A blockchain is basically a continuously growing list of records called blocks that are linked and secured using cryptography.
Again, when a user decides to use a specific type of software for their Bitcoin wallet, they are deciding what direction the Bitcoin network is heading towards. In other words, you need the cooperation of nearly every single user in order to modify any aspect of the Bitcoin protocol.
Payment freedom - It is possible to send and receive bitcoins anywhere in the world at any time. No bank holidays. No borders. No bureaucracy. Bitcoin allows its users to be in full control of their money.
Choose your own fees - There is no fee to receive bitcoins, and many wallets let you control how large a fee to pay when spending. Higher fees can encourage faster confirmation of your transactions. Fees are unrelated to the amount transferred, so it's possible to send 100,000 bitcoins for the same fee it costs to send 1 bitcoin. Additionally, merchant processors exist to assist merchants in processing transactions, converting bitcoins to fiat currency and depositing funds directly into merchants' bank accounts daily. As these services are based on Bitcoin, they can be offered for much lower fees than with PayPal or credit card networks.
Transparent and neutral - All information concerning the Bitcoin money supply itself is readily available on the block chain for anybody to verify and use in real-time. No individual or organization can control or manipulate the Bitcoin protocol because it is cryptographically secure. This allows the core of Bitcoin to be trusted for being completely neutral, transparent and predictable.
Much of the trust in Bitcoin comes from the fact that it requires no trust at all. Bitcoin is fully open-source and decentralized. This means that anyone has access to the entire source code at any time. Any developer in the world can therefore verify exactly how Bitcoin works. All transactions and bitcoins issued into existence can be transparently consulted in real-time by anyone. All payments can be made without reliance on a third party and the whole system is protected by heavily peer-reviewed cryptographic algorithms like those used for online banking. No organization or individual can control Bitcoin, and the network remains secure even if not all of its users can be trusted.
