that whole comparison was too much biased for Spectrcoin.
the same way spectr has OBFS4, CloakCoin has ENIGMA to a whole new way to do anon transactions.
ENIGMA is audited by a security company (COGNOSEC, listed on NASDAQ), Spectr is doing the same error as other coins do, which is bringing up the tech without knowing if it is 100% secure.
We saw this before, every month coins network get hacked because of lack of security, when ppl start to use spectr a lot that will attract attention of hackers, and then we will see if it is really secure.
How is it "biased" ? The table uses privacy related features which are commonly used when comparing any coin. All the listed coins, XSPEC as well, has many additional features which are not listed. Given this generic nature of the comparison, I believe it even underplays what XSPEC has to offer, not the otherway around.
Also, given that XSPEC is built into TOR with OBSF4, it "inherits" the respective security features. Don't know what the user base of ENIGMA is, but I bet it does not come close to those using TOR and therefore providing "audit" of the security aspects on an ongoing basis.
