The 51% “attack” he is referring to is that a mining pool briefly had over 50% of the total hash rate. No attack took place, and within hours miners had moved to other pools bringing the hash rate of the 51% pool down to the mid-30s%. I’ll also mention that the power of 51% attacks is largely overstated too, especially in a privacy coin like Monero.
Even a reportedly private ‘cryptocurrency’ called ‘Grin’ had an attack which rendered the coin useless.
The only usecase of privacy coins is for illegitimate purposes only.
Also: I think you mean ‘CipherTrace‘, ‘CypherTrace’ does not exist.
