Sadly, outsiders never get to know about stuff like that except their circle of trusted friends, until it happens upon us. Elon Musk will surely make a token price spike if people knew he was behind it but the extent of rise is what we may not know until it happens. We saw what happened to Shib and Dogecoin because of his tweets. It even happened when he tweeted about Bitcoin. We saw how price went north because of that. I once held ESH, its price remained down until late John McAfee promoted it and price went off the hook. It's the same way I envisage price will go ballistic if Musk openly promoted any token. For crying out loud, Musk is the richest man on earth and he surely must have influence too.
