Is bitcoin.com legit?

Bitcoin has no official government or central intermediary. The “trust” is based on an open system of cryptology. Numerous accountants known as “miners” look at the “open ledger” to verify that the transaction is legitimate. The first one to verify the legitimacy of a transaction collects a small fee after confirmation and agreement by a certain number of other miners. It truly becomes a "circle of trust." Without digressing too far, just for S&Gs, I looked into mining with one of my old PCs. I quickly learned that it’s not that easy. It would take approximately 1 million years to “mine” one Bitcoin. And, I’m assuming that they are talking about a newer PC!

How does Bitcoin work?

Each Bitcoin is basically a computer file which is stored in a 'digital wallet' app on a smartphone or computer.

People can send Bitcoins (or part of one) to your digital wallet, and you can send Bitcoins to other people.

Every single transaction is recorded in a public list called the blockchain.

This makes it possible to trace the history of Bitcoins to stop people from spending coins they do not own, making copies or undo-ing transactions.

How do people get Bitcoins?

There are three main ways people get Bitcoins.

• You can buy Bitcoins using 'real' money.
• You can sell things and let people pay you with Bitcoins.
• Or they can be created using a computer.

How are new Bitcoins created?

In order for the Bitcoin system to work, people can make their computer process transactions for everybody.

The computers are made to work out incredibly difficult sums. Occasionally they are rewarded with a Bitcoin for the owner to keep.

People set up powerful computers just to try and get Bitcoins. This is called mining.

But the sums are becoming more and more difficult to stop too many Bitcoins being generated.

If you started mining now it could be years before you got a single Bitcoin.

You could end up spending more money on electricity for your computer than the Bitcoin would be worth.
