This chart can answer that question for any period you choose:
Measured in BTC, the average transaction value was naturally the highest in the early days of bitcoin when its value was much less in fiat terms
not sure what you mean by logarithmic graph. The time in a logarithmic scale, or the value? On both, there is a "log" button below the graph. And you can export as CSV or JSON:
As mentioned, raw transactions are incredibly easy to screw up since you must explicitly pay yourself if you want change.
Here's a few scenarios besides unbalanced outputs which will produce huge transaction (Tx) fees:
forgetting to pay change
forgetting to convert to Satoshis in your code
misplacing the decimal (perhaps due to rounding errors)
The blue bars indicate the transaction volume in that period, this is how many bitcoins have been traded. Use the blue numbers at the left axis to see how many bitcoins were traded.
The yellow line is the average weighted price in that period. Use the yellow numbers on the right to see what the price is.
The green and red parts show the fluctuations (high &...
It simply is someone with a lot of coins, who sold on the open market and depressed the price (temporarily). It was an economically unwise decision, since they missed out on the fair market value as you saw.
This is one example of how the Powerful Elite can Thwart Cryptocurrencies.
At the end of the Day this is a very trader specific questions. Trading with a moving average system is dependent on the traders preference. If you do not understand the best way you personally should be trading, you are likely setting yourself up for failure from the beginning. I recommend you read "Trading for a Living" Dr. Van K Tharpe

I wrote a bitcoin price theory is about a correlation of number of bitcoin addresses
(from blockchain) and the bitcoin price, with a law of networking use like the metcalfe law.
here I posted my study about your question
Speaking as a programmer, it's VERY easy to screw up the transaction fee. If you're not using a known bitcoin client and are making your own, it's quite easy to accidentally leave out an output or calculate things wrong. The blockchain won't accept your transaction if you're spending more than the inputs, but will happily accept transactions if you're ...
It would seem using a large Tx fee is an attack vector in that miners will all realign to try and solve the block at height n, which is quite different to the normal situation where it's usually two chains competing for length. The outcome requires 100% "rational actors" trying to mine the block height n and the ability of the nodes to detect the errantly/...
How to determine the Software (Core, Classic, XT, etc.) and quantity
on the whole network?
connect to host and take the 'user-agent' string from 'version' packet
How to determine the last 1k blocks and their Miner Software?
the miner can be determined by analyzing coinbase transaction.
the software can not be determined
EDIT: perhaps what I am seeing is due to different graph scales for the two values?
Yes, these two values are plotted on the same graph, but against different axis. Which line is higher/lower on the graph relative to the other is of no real interest.
Looking at the site in question, I can currently see that the y-axis on the left lists the 'Market cap', ...
Unix Time, Price, Amount of Value in the Order Book at Corresponding price.
So the first line in your example translates to Thursday, April 23, 2015 GMT time, there was an order for 0.01 bitcoins at the price of $300.
I agree with Donely that https://blockchain.info/charts is probably what you are looking for.
Here are some other sites that I refer to for blockchain stats.
https://tradeblock.com/bitcoin/historical - Gives you historical transaction volume
https://blockchair.com/ - A block explorer that let's you query more details. You could probably create a historical ...
Yeah what your saying makes a lot of sense. Blockchain info graphs offers allot of charts to show the data that you are referring to. Do you want something in more detail, if so there are probably some api's around that you can use to your hearts desire.
You're not missing anything. If the two where sourced from the same full node, they should show the same data. It appears that there are two distinct sources used for the graphs.
By the way, the mempool chart indicates that the full node sourcing the chart was uncleanly shut down today, which is not reflected in the other unconfirmed transaction count. On ...
If you look closely you can read the URL: The chart in the video appears to be the Bitcoin/USD chart for Coinbase on Tradingview.com, while theme seems to be set to dark.
Another site used in the video is coinmarketcap.com.
There is no central market for the bitcoin or other altcoins.
Crypto currencies are exchanged on each exchange for the price set by people transacting there. This means that the price is set exchange by exchange, not centrally for every coin.
Thus the variance of the graphs.
It's not clear which API call that you are using so I'll give my two ideas on what the problem might be:
If you are using the "getmarketsummary" API call and calling that
every minute then you will get wrong data because this is based on
24-hours. In my opinion, this is a useless feature.
If you are getting the market trades and then calculating the OHLCV
I think you are viewing the metric incorrectly. The notion of Bitcoin Days Destroyed is not relative to any other standard of measure. Rather, it is the standard of measure.
To clarify, there is no "gold standard" for Bitcoin Days Destroyed saying "if all Bitcoins had been spent within X weeks the total would be Y". That just doesn't make any sense. Think ...
263.95 [USD/BTC] / 233.56 [USD/BTC] * 1 [BTC] = 1.13 [BTC], i.e. for each BTC you sold at the higher price, you can rebuy 1.13 BTC at the lower price.
The underlying concept is explained on Wikipedia: Cross-multiplication.
All of the exchanges have APIs http://pubapi.cryptsy.com/api.php?method=singlemarketdata&marketid=155
you can create a script to keep the numbers updated with wget and a cron job
Cryptsy has a pusher API for live updates.
Different exchanges will offer different rates at the same time because of variations in trading volume, markets, etc. This happens in real currency markets, as well. With enough money it is even possible to play the currency market, "buying" dollars with Euros, then buying yen with dollars, then buying euros with yen, and coming out ahead.
