You have some weird ideas.
For one, while tx volume and hash rate might be correlated, there's no direct connection.
So starting off I'm pretty sure you're not terribly informed.
Also, while a 51% may be easier to execute "that's why they asked miners to leave pools...?"
This is nonsensical.
Ill give to the 5-7% though. 25k *actual economic txs* per day is still awesome.
