                                         What Is Bitcoin?

At its simplest, Bitcoin is either virtual currency or reference to the technology. You can make transactions by check, wiring, or cash. You can also use Bitcoin (or BTC), where you refer the purchaser to your signature, which is a long line of security code encrypted with 16 distinct symbols. The purchaser decodes the code with his smartphone to get your cryptocurrency. Put another way; cryptocurrency is an exchange of digital information that allows you to buy or sell goods and services.The transaction gains its security and trust by running on a peer-to-peer computer network that is similar to Skype, or BitTorrent, a file-sharing system.

What are cryptocurrencies really?

If you take away all the noise around cryptocurrencies and reduce it to a simple definition, you find just limited entries in a database no one can change without fulfilling specific conditions. This may seem ordinary, but, believe it or not: this is exactly how you can define a currency.

Take the money on your bank account: What is it more than entries in a database that can only be changed under specific conditions? You can even take physical coins and notes: What are they else than limited entries in a public physical database that can only be changed if you match the condition than you physically own the coins and notes? Money is all about a verified entry in some kind of database of accounts, balances, and transactions.

How miners create coins and confirm transactions

Let‘s have a look at the mechanism ruling the databases of cryptocurrencies. A cryptocurrency like Bitcoin consists of a network of peers. Every peer has a record of the complete history of all transactions and thus of the balance of every account.

A transaction is a file that says, “Bob gives X Bitcoin to Alice“ and is signed by Bob‘s private key. It‘s basic public key cryptography, nothing special at all. After signed, a transaction is broadcasted in the network.Which is sent from one peer to every other peer. This is basic p2p-technology. Nothing special at all, again.

 

How does Bitcoin work?

Without getting into the technical details, Bitcoin works on a vast public ledger, also called a blockchain, where all confirmed transactions are included as so-called ‘blocks.’ As each block enters the system, it is broadcast to the peer-to-peer computer network of users for validation. In this way, all users are aware of each transaction, which prevents stealing and double-spending, where someone spends the same currency twice. The process also helps blockchain users trust the system.

What do I need to know to protect my Bitcoins?

Here are four pieces of advice that will help your bitcoins go further.

As you’d do with a regular wallet, only store small amounts of bitcoins on your computer, mobile, or server for everyday uses, and keep the remaining part of your funds in a safer environment.

  • Backup your wallet on a regular basis and encrypt your wallet or smartphone with a strong password to protect it from thieves (although, unfortunately, not against keylogging hardware or software).
  • Store some of your bitcoins in an offline wallet disconnected from your network for added security. Think of this as a bank, while you, generally, keep only some of your money in your wallet.
  • Update your software. For added protection, use Bitcoins’ multi-signature feature that allows a transaction to require multiple independent approvals.

 

How do I buy and sell stuff with Bitcoins?

Here’s the funny thing with Bitcoins: there are no physical traces of them as of dollars. All you have  only records of transactions between different addresses.the blockchain record all the increase ande decrease of bitcoins.

To see how the process works, let’s return to Alice.

Example of a Bitcoin transaction

Alice wants to use her Bitcoin to buy pizza from Bob. She’d send him her private “key,” a private sequence of letters and numbers, which contains her source transaction of the coins, amount, and Bob’s digital wallet address. That “address” would be another, this time, the public sequence of letters and numbers. Bob scans the “key” with his smartphone to decode it. At the same time, Alice’s transaction is broadcast to all the other network participants (called “nodes”) on her ledger, and, approximately, ten minutes later, is confirmed, through a process of certain technical and business rules called “mining.” This “mining” process gives Bob a score to know whether or not to proceed with Alice’s transaction.

 

What are the disadvantages of Bitcoin?

Bitcoin got off on the wrong foot by claiming an apocryphal person (or persons), Satoshi Nakamoto as its founder.

Regarding more practical concerns, hacking and scams are the norms. They happen at least once a week and are getting more sophisticated. Bitcoin’s software complexity and the volatility of its currency dissuade many people from using it, while its transactions are frustratingly slow. You’ll have to wait at least ten minutes for your network to approve the transaction. Recently, some Reddit users reported waiting more than one hour for their transactions.

Scams to watch out for

The four most typical Bitcoin scams are Ponzi schemes, mining scams, scam wallets and fraudulent exchanges.

  • Ponzi ScamsPonzi scams, or high-yield investment programs, hook you with higher interest than the prevailing market rate (e.g. 1-2% interest per day) while redirecting your money to the thief’s wallet. They also tend to duck and emerge under different names in order to protect themselves. Keep away from companies that give you Bitcoin addresses for incoming payments rather than the common payment processors such as BitPay or Coinbase.
  • Bitcoin Mining ScamsThese companies will offer to mine outrageous amounts of bitcoin for you. You’ll have to pay them. That’s the last you’ll see of your money (with no bitcoins to show for it, either).
  • Bitcoin Exchange ScamsBitcoin Exchange Scams offer features that the typical bitcoin wallets don’t offer, such as PayPal/Credit Card processing, or better exchange rates. Needless to say, these scams leave you in the hang while they siphon your dollars.
  • Bitcoin Wallet ScamsBitcoin scam wallets are similar to online wallets – with a difference. They’ll ask you for your money. If robbers like the amount, that’s the last you’ll see of your deposit. The address, in other words, leads to them, rather than to you.

Of all of these, wallet scams are the most popular with scammers managing to pinch millions.

What are the advantages of Bitcoin?

The best thing about Bitcoin is that it is decentralized, which means that you can settle international deals without messing around with exchange rates and extra charges. Bitcoin is free from government interference and manipulation, so there’s no Federal Reserve System‍ to hike interest rates. It is also transparent, so you know what is happening with your money. You can start accepting bitcoins instantly, without investing money and energy into details, such as setting up a merchant account or buying credit card processing hardware.no one can refund you your bitcoins
