At 3:33 he says that bitcoin is the future and he believes in it. Does that mean he's not dumping it on the market but holding? I doubt it.
He said something about being 50/50 in bitcoin and fiat. When other Chinese dumpers start doing their thing he's probably wetting the bed
It might be just like the forums, people starting threads that they sold their houses to buy bitcoin, just to get people believe and not sell as well
