I'm interested in knowing how many bitcoins miners harvest for transaction fees ... week/day/year is fine if I can also figure out the # and avg transaction amount. I know this info has to have been studied before. Can anybody point me somewhere?
It depends. Sometimes it is 0 for fees other times it is like .3 btc total sometimes it can be higher and it most likely averages .1 or a little less btc in transaction fees per block.
If you look at blockchain.info it and click on the blocks you can see the transaction fee.
