Elon Mask’s tweets in Twitter sometimes are so misty that it’s hard to make right conclusions for a not privy person. So this words that he is going to quit all his works and "become an influencer full-time wdyt” can mean whatever. But they sound like someone hurt his feelings a lot. This tweet he wrote soon after the news from Nasa (at the beginning of December) that research on technology for space exploration and planets exploration (Moon and Mars) by humans will be ended not earlier then in 2034 and ISS will end exploitation in 2030. So Elon's dreams and promises about manned space missions to other planets have become unreal. Possibly that is why he is leaving his works. But nevertheless he will still be an influencer for all his followers. No one can say you exactly how Elon's decision will influence on crypto. Only time will show (and possibly some other Elon tweets).
