Honestly these type of news always happen and talked about, and yet I have never seen anything bad come out of it. Nobody really cares, what the market cares about is superficial idiotic things, not the real movements and that's a bit sad. 10K bitcoins moved and nobody cares about it, watch how Elon could ruin or increase the market tomorrow if he decided to do it. That is a sad reality but he can, with just a single tweet for example.
This is a proof that people care about what they can't control, and do not care about the tangible real things that they can see. I would personally be scared more of this than a tweet, but I am no longer like that, because of the market.
I think you are right and it wasn't always link to mt gox. There are times that they link a thousand of btc to an old inactive wallet that suddenly became active and there are times they think that satoshi is now selling his bitcoins. It wasn't really new to us so we shouldn't worry because news like this are mostly just a rumour.
Let's wait for some days and we will see that it doesn't have any effect in the market and if there are some movements, it can be caused by other things which occurred in real time. There is no need to be scared because we already witnessed the worst in cryptos but despite of that, cryptos are still alive and recovering.
