I think people complaining and being negative is common when their investments are down a lot. I guess there will be more of those types of posts especially now that BTC is going lower. I think what's even worse is when a person sold their assets but are still negative about things, instead of moving on. Some people just like being bitter I guess. I don't know who you're talking about but if they are consistently being negative and is starting to affect you, maybe you need to stop reading their posts for a while, or unfollow them.
