My first comment is that some consultant must have earned a big check by copying some trivial observations, already made many times in this forum, and pasting them into a neatly formatted report with a nice plastic cover.
The "flat transaction profile" that they mention must be
this graph, of the total daily output volume E extracted from the blockchain (according to the site, excluding the outputs that appear to be back-change).
But I have a different explanation for why the E plot is basically "flat". (I don't recall whether I posted this already, sorry if I did). Its current value, about 100'000 BTC/day (50 million USD/day), seems way too big to be actual payments (bitcoins changing hands). Consider that Bitpay claims to have processed only 100 million USD in 2013, when the total E volume, eyeballing from that plot, was at least 3000 million USD. While there must be a lot of BTC payment that does not use Bitpay, the
ratio >30:1 seems excessive.
My theory is that a large fraction of the E volume -- maybe 90% or more -- is "fake", that is, bitcoins moving between addresses that belong to the same person. These could be mixing, hotwallet/coldwallet movements, deposits and withdrawals from exchanges, software testing, etc..
This explanation for the flatness of the E plot may be good news, because it does not exclude the possibility that actual use may be indeed increasing. If 90% of the E volume is fake, even a 100% increase in real usage would be quite hard to see on the E plot.
On the other hand, this theory means that the current cost of the Bitcoin Network, in proportion to actual use, is quite large. If the E volume were 100% actual payments, each payment would have a hidden 4% fee, currently paid by bitcoin holders (as inflation tax) rather than by the actual users. If 90% of the E-volume is fake, that hidden processing fee is 40%.
Clearly, radical adjustments in the network and the nature of the blockchain traffic will have to occur while the protocol switches from block rewards to transaction fees, if bitcoin is to remain competitive with bank transfers and credit cards.
