Nothing was added. It was just bitcoin price going up while shitcoins dumping a little instead of a lot so it creates the illusion that their USD price is rising but that is all because bitcoin price went up and they get dumped less than that rise against bitcoin.
Some nonsense ELON FUD made a dump and after that everything is going smoothly.
Only a very small part of the drop at the start was because of Elon FUD, the rest was a lot more complicated market manipulation than one man's Twitter crap.
