Coming from a founder of a social media giant, any of his statement towards bitcoin will surely boost its popularity and good impression, well as long as the statement will stay positive. Support from big personalities will change the negative views of other people about bitcoin especially those who always tagged it as a "scam".

However, people should not take it as one of their criteria and reference in terms of making their next strategy. Don't also take that as the main reason why the price is surging today.
