Can someone explain how 80k bitcoin showed up on Coinbase last night?

look at the 24h changes? looks like it moved from Kraken and others?
didn't Germany "release" their 50k coins via Kraken?
The timing is interesting for sure. I just found this

could be someone providing liquidity to coin base. Especially with the SBR and all this stuff in the air, I think the US wants to start buying cheap BTC.
I agree ☝️. Sometimes is in the works. I also believe people getting liquidated, as a benevolent entity to bring fresh coins to the market.
