Lol, I have seen some of that behavior around and I do act sometimes like that.
What can I say, there is so much to do, and we all are a bit guilty of doing a few things we don't like.

I am sure people buy tribe tokens in hope that they will get better returns, and maybe in future, they can sell them and accumulate more hive.

I don't buy much. Just a few game tokens that I like to play. Dcity, Dcrops, and recently risingstars and splinterlands.
I think play to earn games will be big in future, just don't know which ones.

Plus it's always fun to do something else than to write and engage. And sometimes talk about different things.😅

What can I say, I am addicted to all these games, and keep a tab open to play some of them in the background😅
