I think that the crypto world does not care much about what Musk does since he screw up his position when he first promised to sell Tesla cars for Bitcoin and soon after he retired from that statement with a strange reason we all know,that Bitcoin mining consumes a lot of energy.
He will come back and his tweets will have effects again but now very little effects. I think in next bull run, we will see Elon Musk showing his tweets and effects on crypto market again. With his big capital, he can play games in crypto again.
I don't believe Elon will leave crypto market in future. It is addictive enough for him to stay.
Since then no one takes him seriously anymore and I think this is the right thing to do.He tried with several other coins to pump and dump like Doge,Shiba and a couple of others that are now largely unsuccessful,so not much will change for FUN even if he tweets that he buys FUN token.
I think we can only connect Elon Musk with Bitcoin and Dogecoin. For other coins, I don't know he actually involves in. Maybe he made funny tweets and market makers us them to pump those shit coins. If Elon tweets FUN, people will search on the market to find what is a FUN token/ coin?
