then for what is bitcoins used? what do you think? just for trading?

and other way to measure the usage could be to monitor DNM. To become a feeling of the amount of BTC this is used to buy things.

What are the uses of fiat currency ,you can trade ,purchase things and so on and that is the exact use of bitcoin and people use it for many different things and it is really impossible to find out what percentage is used for what and so on,but every transaction are in the ledger.

I think he is talking about buying things separated used for buy things and separated for other things. ? am i right op..
I think there is no other site that can give you such information only blockchain can gives you all transactions. history. bitpay can not gives you all transaction history for buying things..

There's no way to find it out, bitcoin is currency and an investment. We cannot determine if a transaction is from trading or buying of goods and services. Just like in fiat, we can use it for everything as usual the same thing with bitcoin. And I guess there's no need or help for doing this type of research and additional knowledge.

Its all upto the product you want to buy in online site where btc accepts. Even you can make 5$ recharge for your phone via bitrefill site through out the world. If you wish to use btc in online I suggest you to sign up in purse.io site where you can purchase all the things in amazon via this site.
If you are using btc means you eligible for 15% discount for any of your order.

We can't really trace the real btc usage. There is no such counter that detects the exact numbers or even estimate. We already know and notice that bitcoin is already accepted and used by many countries, mostly probably and there are lot of online merchants that adopt and supports bitcoin for their business.

first visit their website (bitpay or any of others) and see if they have some kind of statistics on their website, if not you can contact them and ask them nicely if they could release some statistics in their blog or on their website.
for example some bar chart showing the amount of bitcoin that was sent through bitpay or any other merchants each month/week/day

edit: did a quick google search for "bitpay stats" and this came up:

Here's an idea.

Blockchain.info has some great, basic charts and stats about bitcoin. Let's use this data to come up with an equation.

Here's what we need:

• Total amount of bitcoin in existence (market capitalization, A)
• Total amount of bitcoin that is transacted over a period of time (transaction monetary volume, B)
• Number of days between new transactions for each bitcoin (transaction turnover, C)

The equation is (B * C) A = percentage of Bitcoin used for purchases of goods/services.

1) The market capitalization represents the value of all the bitcoin that's been mined. Today that number is $18.7B (https://blockchain.info/charts/market-cap)

2) Let's assume that nearly all of the transaction monetary volume in any given day is used to buy goods or services. Bitcoin that's being saved or hodled (if you prefer) doesn't exchange wallets. The transaction volume (exchange traded volume per day) ranges from $6M to $111M between late 2013 and current (when activity started to pick up consistently). Now this is a daily number so we need to find a median - simply the median between these two numbers is $58.5M. So on average the daily transaction volume is above or below $58.5M

3) Let's assume that the transaction turnover, the amount of time between purchases for goods/services with the same bitcoin is 1 transaction per week. If we multiply the $58.5 median daily volume by 7 days, we get $405M. This is our average amount of bitcoin used to purchase goods and services.

So, ($58.5M * 7) $18.7B equals 2%.

With these rough assumptions I'm saying 2% of the bitcoin in existence is used for purchasing goods over any 7 day period.

What do you think? This seems low to me. Let's debate how we could change the assumptions and let's start with how much time (on average) exists between two transactions with the same bitcoin. If we increase that number, we increase the percentage.

what? i had to step in here, because what you said it's wrong on so many level, bitcoin usage of course must be measured with the purchase you made with it

not with dumping for fiat or trading, or anything else, after all bitcoin is also a currency not only a tool for speculators or store of wealth


this don't really tell us how many bitcoin are being used to purchase stuff with them, those transaction can be very small like 0.01-0.1 range

it's better if you see the amount of bitcoin sent throught bitpay
