About 2 months ago Roger Ver spoke about the split of Bitcoin Cash and BSV.
Since then Bitcoin's price dropped from $6,500 to the $3,000 area.
Which statement are you referring too? The earliest comment I found from Roger Ver about BCH / BSV was mid- to late November, ie. when Bitcoin already hit the 3000s.
In general I don't think Roger Ver's comments have much influence on Bitcoin's price.
