LXC has been great and there is definitely much more room for upside potential. The first coin with a mobile PoS wallet is something the team should be proud of.
There has been accusations of Root being a scam from a few folks including earlz (Bittrex's right hand man) - he questioned the instamine at the beginning which was around 475 blocks worth around 40k ROOT. bitsta confirmed with the community that the instamine was in fact miners who got in early, and that is understandable. BitKey is really the highlight of RootCoin and bitsta has promised a beta launch sometime this month. It will be interesting to see how the technology compares with other established anonymous/privacy coins, either way, it brings something new to the table for crypto-currencies.
I don't follow Twitter much but will have a look into CaptCoin.
This is true about LXC, I recommend it as a buy despite it being high already. The mobile PoS wallet is definitely an accomplishment.
Yes, CaptCoin is still somewhat questionable for me. I personally will buy some, but I am still hesitant to recommend it.
As for ROOT, I have heard those scam stories as previously stated. It's reassuring to know that the mining was due to outside miners. Despite scams, I have accepted them as part of the game for now and I read them well, so you can still profit. hehe
Also, twitter is full of hype, at the same time, I find really instant news from a bunch of sources as opposed to some other websites/bitcointalk.
