On January 18th, there was an interesting clarification— the founder of a leading exchange denied the gossip about his relationship with a certain actress on social media. He said he doesn't really participate in social activities and has never met the actress. The topic went off-topic, and he also casually criticized a phenomenon: now everywhere are "news" that are hard to distinguish between true and false. It’s increasingly difficult to tell which to believe and which to ignore. However, he offered a suggestion— if you can master this "fake news filter" skill, your account will thank you.
