Not really a thorough paper: For example it's missing the probably most lucrative attack vector: Buying put options on the two assets and then engineering a 51% or 34% attack. It also doesn't thoroughly dispel concerns regarding the continuously diminishing fees earned by BTC miners (which require a doubling of the price every 4 years to keep fiat returns the same) - the simple lack of a correlation between hash rate and fees is not convincing (miners probably mostly look at the price and plan more long term).
