Is there a Bitcoin supply limit?

Bitcoins are created by the process called “mining.”
Bitcoins are created/minded for a fixed rate every time a new block of transactions is created.
Blocks are created every 10 minutes.
The block reward started at 50 BTC in 2009, and it gets halved every four years.
Currently, the block reward is set at 12,5 BTC.
There mining of Bitcoin – the total supply of Bitcoin is limited to 21 Million.
This limit is hardcoded into the protocol and cannot be changed.
Changing the supply by your own is equal to attacking the Bitcoin network.

What is a Bitcoin wallet?

A Bitcoin wallet is a piece of software that stores the user’s private keys.
Your bitcoin wallet allows you to access your Bitcoin.
These wallets communicate with the Bitcoin network every time you want to send or receive Bitcoin.
Please note: Bitcoins are not stored in your wallet!
Only your private key is stored in your wallet.
If you lose the private key, you lose access to your Bitcoin, and will never be able to access it again, and it will be lost forever.
Backup your private key!


What is a private key?

Your wallet never stores any bitcoins.
The only purpose of a wallet is to keep your private key and communicate with the Bitcoin network.
The private key is a long string of random numbers and letters, and it is always paired with a Bitcoin address.
It creates signatures that are required to spend your funds by proving that you are the owner of the funds used in the transaction.
Losing access to the private key is equal setting your cash on fire.


Which Bitcoin wallets are safe?

Different types of wallets offer a different level of security.
There is are tradeoffs between usability and accessibility.
The least secure wallets are the online wallets, and the most secure ones are the hardware wallets, and paper wallets also called “cold storage.”

Some Bitcoin exchanges trade BTC against USDT. What is USDT?

Online exchanges like Poloniex don’t use real USD dollars for trading.
Instead of USD they use USDT  – a USD token – easily exchangeable P2P just like Bitcoin.
USDT is an asset-backed token which means that every unit of USDT is backed by one real US dollar. The units of USDT are called tethers.  Each tether represents one real US dollar.
Some exchanges prefer using USDT because of the easier integration compared to real USD.
As opposed to international bank transfers, Tether tokens can also be transferred internationally at almost no costs.


How can I start trading Bitcoin?

Register on online exchanges dedicated to cryptocurrency trading.
Registration on such platforms requires users to send a copy of their government-issued ID.
The validation process could take up to few weeks depending on the user influx.
Examples of Bitcoin exchanges: Bitstamp, Gdax, Kraken, Gemini, Bittrex.


Is there a Bitcoin CEO?

Bitcoin is a Decentralized Autonomous Organization (DAO) and is governed by the community.
Bitcoin lacks traditional top-down structure. Bitcoin is not a company registered in any country.
Bitcoin is a software protocol which lives on the internet.


What are transaction fees?

Each time users send bitcoins a transaction fee has to be paid.
These fees are not fixed and depend on the network load.
If there is a huge transaction spike the transaction fees increase accordingly.
Currently, the Bitcoin network can process a handful of transactions, and any usage increase reflects on the fee price.
The Bitcoin community is working towards solving the problem.


Why are Bitcoin transaction fees so high?

Bitcoin fees are dynamically adjusted.
When there is a usage increase, the fees increase accordingly.
Please refer to “What is a transaction fee?” for more info.


What’s margin trading?

Margin trading is essentially trading with borrowed funds instead of your own.
When you place a margin order, all of the money you are using is borrowed from other users offering their funds as peer-to-peer loans.
The funds in your margin account are used only as collateral for these loans and to settle debts to lenders.

What how do I calculate the Bitcoin Market Cap?

The market capitalization of a cryptocurrency can give you a perspective on how big the market for that currency is.
The current Bitcoin market cap is around USD 41 billion.
In order to calculate it, you need to multiply the today’s price by the total coin supply.

Market Cap = Price x Circulating Supply
$41 538 444 951 = $2526.85 x 16 438 825 BTC
