SpectreCoin have the features to be consider as a privacy coin but not the best in terms of privacy coin because it only has the fully integrated Tor+OBFS4 and the new proof-of-anonymous-stake (PoAS) which was implemented by the team. However, Grin and Monero are consider as the best privacy coin due to the potential they posed.
So what about a lot of accusation for xspec and i thought that never get any reply from the developers. I put a little expectation for xspec.
It's not even the best privacy right now and monero still hold the king of the privacy coin.
For a start, take the trouble to study before unfairly attacking.

Monero is unquestionably a good privacy coin, but spectrecoin is no worse ( wallet works in China)
