Topic: How big is a bitcoin? (Read 2265 times)
There is no set file size for a bitcoin. It does not have to be just one particular size
Bitcoin when consider physical also it does't have a specific size or weight. It purely based on the creator. According to me The bitcoin can be measured only on its value, if so bitcoin is very very.............very big
Yeah, value matters, and not the size, and we all know what value bitcoin holds at a moment, so its the value of bitcoin that makes it bigger and bigger everyday, just remember big things comes in small packages.

Satoshi defined a bitcoin as a chain of digital signatures, so it would have a size.
analogy:
a bank note is just a piece of special paper.. on its own its useless.. without special words connected to it to validate that it is a bank note... its just paper
This is perfect analogy not just for the "size" discussion but for the whole definition of bitcoin and cryptos itself. Well done, sir!
Bitcoins have no size. What is sizeable is the blockchain, and transactions are the ones who take up space.
Yepyep. This is what actually your miners mine for. Blockchains. And these blockchains we sell for companies who use them.
Hey guys, just as the title says, what is the file size for a bitcoin? Does it vary, depending on what coin, or does the file size stay the same? I'm not talking about the size of a wallet.dat file, as those have other information kept inside. I want to know the size of the pure coin.
Does the coin change size the more it is transacted?
Does the coin's size vary if I compare a bitcoin to a litecoin?
thanks for post this,i never think that bitcoin have a size Does the coin change size the more it is transacted?
Does the coin's size vary if I compare a bitcoin to a litecoin?
and now realize that i must be know about that,and some comment give me info,that the size about 256-bit,so small It doesn't have any size dude. It classify according to blocks. Its not segregates with coin or other thing.
Its purely independent without any size consideration.

To me, the size is 256-bit, the size of the private key. You can do anything to the coin(s) with the key.

Danny already gave the best definition of sizes the OP might have been asking about, as he seems to be talking sizes of transactions and not about the private key of any address...
According to me, the size of a coin depends upon how much one sends in a transaction and how much transaction fee is included, as that gets mixed up in a transaction block and those blocks are of different sizes having small and large - both types of transactions and fees...

Ok, Danny proved they're pretty small but how much do they weigh? lol
I'll get to work on that for you, but while I'm at it, I was wondering if you'd happen to know how many angels can dance on the point of point of a very fine needle, without jostling one another?

I can guarantee that if you've been hitting up faucets and collecting enough Satoshis to add up to one Bitcoin then you would have one very large Bitcoin on the blockchain.Here is an actual transaction from the blockchain represented in hexadecimal sending 0.099 BTC to 1NScWjpKqfLkAf2q9tMXhansZQRpM5HUS3 and paying a 0.001 BTC fee, for a total of 0.1 BTC spent from the sender's wallet. It is 192 bytes long. I've color coded each piece of data to match up with my color coded descriptions that follow. Each byte is represented with 2 hexadecimal digits, so the string of numbers and letters below is 384 digits:
You can look at the pieces of the transaction and decide for yourself how big you think "a bitcoin" is. The 8 bytes that franky1 was talking about are seen in the description below where I state:
- 8 bytes indicating quantity of satoshis this output supplies to a transaction if it is used as an input in the future (0000000000970fe0)
But you'll also notice that the representation of the 0.01 BTC that is being spent is handled by 36 bytes that refer back to where the output was created, and the new 0.099 BTC output that is created by this transaction doesn't exist unless this entire 192 byte transaction exists.

(Note: Transactions in hex are typically represented in little-endian byte order. This transaction has been converted to big-endian byte order so that the conversions from hex to decimal won't be as confusing to those that are unfamiliar with the differences between the two representations.)063c72a0b4000000076b483045022100e25ca2d2d56e50df86837a865184a1ef3

I think the more sources a coin have the larger it is... So for example a newly mined coin would be much smaller than a coin that has been circulated for years.
bitcoin is no size .

bitcoin is no size . bitcoin is only depended on coin not size and we can see bitcoin size and after coin. how much price increase every day. only we can see
Doesn't really have a size. In terms of cash it does. About 300-400 USD right now
is the point of this question will result to have a program calculating file size?
what like 1mb per 25btc block solved..
but thats hard to measure as couple years ago a block gave 50btc and had less than 0.4btc average..
next year the block limit will increase and the reward will halve..
and if your not going to just calculate the block reward vs the block.. and just wait till 2014 and then divide 21m by the total chain size.. that wont work either as transactions spend the exact same satoshi's many times a year.
the best logical answer is that a satoshi 1 is one byte and bitcoin is 100000000 9 bytes as recognised behind the scenes in the code.. or 10 bytes 1.00000000 as recognised front end in the gui
and you'd have to re-edit the codes every halving.
Well, perhaps the way to put a size on it is to determine how much does the blockchain grows once a new Bitcoin is generated. The size of that initial transaction that creates the Bitcoin might be considered the "base" size of a Bitcoin.
If all Bitcoins were mined and they were not transferred (just locally to the miner's wallet) blockchain will still have a certain size. If we divided that size by the number of bitcoins... would not that be the (minimum) size of a Bitcoin?
