I do think his comments slightly affect the bitcoin market (most probably the small investors). But as of moment, the value of btc is up by around 7% from yesterday. The small investors are the mostly affected by this comments of Trump because it might put some questions in their minds.

But for the whales and big investors, Trump's statement about bitcoin and other crypto is just a mere opinion. These whales know what they are doing (considering they're crypto experts), and that there's nothing to fear about what Trump has said.

Also, bitcoin is expected to make another leap in value IF Facebook's crypto survives congress hearings.
