XMR is way better as it is a real asset and its not tied to pump groups like this one for what i see
It's going to be dead when the chain gets too big. Now what coin is working on a technology to actually shrink a block chain?
Hint: it's going to be in zk-snarks.
Which have huge block chain bloat issues of their own. Worse than rig sigs. Also they are basically zerocash (of the zerocoin/cash twins) which has a massive fatal issue. You have to trust the dev to destroy the key that creates the coins. If dev doesn't destroy it or keeps copies he can mint as many coins as he please to dump on your head anytime he wants. Do you trust SDC's devto do this after all the crap they pulled?
