This remained a rumor, unless you can provide a valid evidence that Satoshi is actually back. But I don’t see any validity from your post, to be honest. It’s like you are just promoting this coin in the forum while you spread a rumor like Satoshi is back which I don’t see it happening right now.
And during that time that bitcoin has dropped below $80k, I guess it’s all about Trump and that many bitcoin investors are selling in the market so it’s expected that bitcoin price will experience a decline. However, with Satoshi thing, I don’t think he’ll ever come back in the forum again, and if ever he will, none of us will know about that.
You are right to doubt claims about Satoshi Nakamoto return as there is no real proof and such rumors are mostly just ways to promote coin. If Satoshi ever came back it would be with clear technical evidence, not simple post. If Bitcoin price drops below $80000 so this will be due to real world factors such as Donald Trump trade policies causing market uncertainty and investors selling off assets other than anything to do with Satoshi. It is very rare chances that Satoshi will ever reappear publicly as their anonymity clearly showing Bitcoin decentralized nature and any true return would be game changer.
