Those who are spreading FUDs during every halving are those people that's been left out because they are always being hesitant buying Bitcoin when it was still on the dump season. So instead of congratulating those people that didn't doubt Bitcoin, they are trying to brainwash them by feeding negative thoughts.

Though, for me I always ignore those people since their opinion doesn't matter to me at all. What's important is that I always have Bitcoin on hodl for the biggest moment.
