You fail at reading a graph (in your defense, the data is noisy). But smooth it by looking at the quarterly averages and it is clear there was a +40% growth from 45k to 65k transaction/day over the last year: http://i.imgur.com/XJs4V74.png (or see www.quandl.com/BCHAIN/NTRAN-Bitcoin-Number-of-Transactions and select "quarterly".)

No, I didn't fail at reading anything. The increase is both within the noise of the data and insignificant. 20K transactions is nothing, hell given the number of BTC that are "washed" through pools, one person could easily account for 5K of those transactions.

+40% is significant (insignificance would be <5%).

If it really was noise, http://i.imgur.com/XJs4V74.png wouldn't show a relatively smooth exponential-looking curve.

Are you really arguing that a pitiful increase of 20K over a year, in a system where every single change in any holdings causes a transaction to occur, is significant for this system? I shudder to think of the reality distortion field you live in.

For sake of argument, let's say that coinbase keeps 100 small, hot wallets around. Every time coinbase rearranges funds in their wallets, they could create between 1 and infinity transactions. If, on average, they rearrange funds daily in such a way that 25 transactions occurs, they would account for 50% of your increase alone.

Given that all exchanges and processors routinely shuffle funds around, and every move is recorded as a transaction, you need exchanges (in total) to make 55 more transactions/day to make up your superduper exponential growth.

20K increase in transactions in bitcoin is no increase in transactions.

Your math is way off. It is 20k transaction PER DAY. 5.9 MILLION transactions were processed in 2014Q2, up from 4.1 MILLION in 2013Q2. That is an increase of 1.8 MILLION!
