No one knows what will happen. Everyone is free to say he's opinion. The bitcoin is not the only "coin" in the world. Today, we can't predict for sure if tomorrow we will be alive or dead. How sure can we be for thinks like that? The people who knows about the world economy market, i don't think they use the internet as "users".
The parameters are too many, and a ordinary human can only assume and not predict the economy.
We all here, are playing the same game, with the + and - of it.
