I have spent two hours reading about how to start and what bitcoins are and unfortunately nothing is really clicking.
I understand that I must obtain a wallet and then purchase coins to put in it, then use that as payment. Where I get confused is when everyone starts talking about the price of bitcoins and exchange and fluctuation. I feel like I need a series 7 to understand it.
Example: I want to make, say, $100 USD purchase. So the current price of a bitcoin is $629... obviously Im not required to spend $62,900 to make a $100 purchase. Can someone explain how this part works for me? I feel stupid like this should be obvious to me but it just isn't. And can someone explain this in a way that I can apply it to any purchase, so that I can look at any purchase price and figure out how many bitcoins (satoshi) are needed?
Thank you!

Hi there alkb,
Welcome to the wonderful world of Bitcoin!
Things can be a little confusing at first because of how innovative Bitcoin as a technology is, but rest assured once you get the basics the rest falls into place incredibly easily. Just a little tip to help ease you into things, when describing the technology itself - Bitcoin - it is usually written with an upper-case 'B'. The units of currency, "bitcoins" or a single "Bitcoin", are usually written with a lower-case 'b' for plural, or upper-case 'B' for singular. This is in no way important, it's just in case you're wondering why I capitalize some words and don't capitalize others!
To briefly answer your question, bitcoins are divisible down to 8 decimal places so you don't actually have to purchase a whole bitcoin.
To clarify using your example:
You want to purchase
$100 worth of Bitcoin.
The current price of one Bitcoin is
$757.76
100$ worth of Bitcoin =
0.131967905 BTC.
You can determine how much Bitcoin you will get for any amount by dividing the current price into that amount, so for $100 worth of Bitcoin we just divide $100 by $757.56 = 0.131967905 bitcoins.
You'll find everything you need to get you started by clicking the '
Start here' link in the menu bar at the top of this page.
You can see the current value in USD on a little 'ticker' beside the menu button in the top right corner of any page on the Bitcoin.com website. You can also use the Price Converter on our
Tools page. Note that the price may vary slightly between these two due to them being sourced from different
Bitcoin exchanges, but the difference will be negligible.
Please be sure only to buy bitcoins from reputable exchanges and individuals; a fairly thorough list of exchanges can be found on our Bitcoin exchanges page linked above. You can also buy bitcoins with a credit card on our '
Buy Bitcoin now' page.
To go a little deeper into things regarding smaller units of Bitcoin, this works similar to the way Dollars and cents work.
For example, you have 1 Dollar which consists of 100 cents. So the
Dollar is divisible to
2 decimal places. However,
Bitcoin is divisible to
8 decimal places. So where the smallest amount of Dollars you can have is 1 hundredth of a Dollar (1 cent), the smallest amount of Bitcoin you can have is 1 hundred millionth of a bitcoin (1 satoshi).
1 satoshi is the smallest possible piece of a Bitcoin and allows for transactions to occur that are much smaller than a full bitcoin, and there are 100,000,000 satoshis in every Bitcoin. That being said, Bitcoin is most commonly expressed in one of three denominations.
Let's pretend for a moment that 1 bitcoin = $700:
Bitcoin – BTC – (1 full Bitcoin) - 1 BTC = $700
milliBitcoin – mBTC – (1 thousandth of a bitcoin) - 0.001 BTC = $0.70
microBitcoin – uBTC – (1 millionth of a bitcoin) - 0.000001 BTC = $0.0007
Just in case you're wondering about a
satoshi - (1 hundred millionth of a bitcoin) - 0.00000001 BTC = $0.000007
Generally speaking, you'll only really talk about Bitcoin in terms of whole bitcoins and milliBitcoins.
Don't worry about the details above too much though; once you get set up with a wallet and receive your first bitcoins it'll all become a lot clearer!
