/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.
Did have some some pretty good discussions over on Steemit, they have quite a lot of active Discord groups that are tied to particular groups.
unfortunately this is true about every social media platform that people could sign up on and spam in. and that is all thanks to altcoins and their pump and dumps. there is an army of bag holders who think if they advertise the shitcoin they are bag holding they can make back what they have lost so far.
if they spend half the time they spam to learning how the market works they would never lost any money anymore.
as for steemit, i personally don't like it. they mixed money with posting so it became corrupted. now whenever i see a post on steemit my first assumption is that it is a low quality post made to earn money and i prefer not to waste my time.
