This is normal. Here you can see a chart of average transacted value every day: https://blockchair.com/bitcoin/charts/average-transaction-amount-btc
There are 2 things that contribute to this:
The very large transactions skewing the numbers. This becomes more apparent if you take a look at the median transaction values, which are around the 0.02-0.03 BTC ...
There's several anti-DOS measures that counter this:
transaction fees get expensive with large numbers of outputs
many rapid transactions with no fees will be rejected
small amounts (less than 0.000045) in an output are called dust, and are rejected
It essentially becomes prohibitively expensive to try to spam.
This question could be asked of any financial instrument. Volumes decreasing is not a bad or good sign. It's simply something that occurs when volatility decreases. The market theory behind it might go like this.. Price has fallen to such low points sellers are no longer interested in selling. Buyers are still hoping for lower prices. This effect causes the ...
cryptocompare has the utility you need.
Go to Coins at the top, find your coin
Change the bar graph at the bottom to display by Hour
Use the interface to see the volume per second
If this is too unwieldy, cryptocompare does have an api and a useful npm package to play around with.
I am assuming you are asking for trading volume across exchanges.
Brave New Coin (BLX) provides a good API to get volume weighed average across major exchanges: https://bravenewcoin.com/data-and-charts/indices/blx
You can also see their chart with volume on Trading View (look for BLX ticker): https://www.tradingview.com/chart/?symbol=BNC:BLX
I can't answer for the discrepancy that you're seeing, but the "right" way to calculate volume would be to add the "total" column from each trade that occurred during the period. That is, assuming that candle charts are based on stock market candle charts.
It doesn't surprise me that you're seeing this discrepancy, however. I've noticed a few different ...
It connects to the api of the exchange and returns the traded volume.
The volume of the exchange is the sum of all coin's volume in that exchange that is returned from the exchange API.
The volume of the coin is the sum of that coin's traded volume that is returned from all exchange's api.
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
Who bears the burden of the cost ? Is it the user or is it the network?
Just like what happens when more dollars are printed, the value of all the existing currency goes down.
If its borne by the network, wouldn't this cause an increase in circulation of bitcoins in a network and lead to reduction in their value making them unstable?
It leads to a ...
It just depend on the site you are seeing, on market charts/stats (like http://bitcoincharts.com/ or http://bitcointicker.co/) volume refers to trade volume, which indeed is not the money sent to the exchange, it is the BTC that changed hands inside the platform (there is no need to come from external and the same "coin" can be traded several times a day).
