I guess SYNC will continue to fall despite the POS, is very different from the DRK ..
Just wait n see
After the suggestion of adding anonymizer that's when I agreed to look into possibility of adding anonymity and looked right into Monero but it can't work with Sync since it has different algo.
Adding anonymizer will not work overnight and even Darksend is not yet completed from what I know. It will take time to add working anonymity but it is possible.
Within next few weeks, I will confirm what I'm working on.
Edit: We even had higher hashrate than Darkcoin. I believed in Proof-of-Work than Proof-of-Promise
