I believe this was just pure market speculation and no basis for its dump. And I don't believe anyone who will say like this because, in the first place nobody knows exactly what will happen today, tomorrow and for the incoming.
Of course nobody should make investment decisions based on this information. This is pure speculation, and in fact anything can happen. What we write about here is only what we believe. The cryptocurrency market is too liquid to be sure of anything.
If someone invests long-term, they should not read it at all. However, if someone invests in short term, then they should be careful, because in my opinion a hard dump of price before halving is very possible.
