/r/CryptoCurrency/ is such a weird place, you can't really expect to have any sort of serious discussion there.
When you look at that sub, it seems as though it's full of children. Some of the comments are just atrocious.
The Daily Thread on
https://reddit.com/r/BitcoinMarkets/ is the best place for intelligent discussion on bitcoin. They moderate it well, so the silly/scammy stuff is absent.
