From here, number of daily transaction
https://blockchain.info/charts/n-transactions
can i say, for April 2014, average daily transaction is around 60,000 ?

From here, bitcoin estimated usd transaction volume :
https://blockchain.info/charts/estimated-transaction-volume-usd?timespan=30days&showDataPoints=false&daysAverageString=1&show_header=true&scale=0&address=
can i say, the average is about 50 million USD  ?

So, an average transaction is about = 50 million /  60,000 = $ 833 USD
So, it's about 1.7 BTC  ( assume 1 BTC = 481 USD )

Is my understanding correct ?
Can you advise ?

thanks
