There is a BTC wallet that just moved ~$1 Billion USD. Here’s the address and the search results for BTC, BCH and BSV from blockchair.com:
1HQ3Go3ggs8pFnXuHVHRytPCq5fGG8Hbhx
Due to the age of this address the owner has coins on BTC, BCH and BSV.
These transactions are only a few hours old but so far the BTC and BCH have moved while the BSV is still held in place.
What does that tell you?
EDIT: the BSV has moved. https://whatsonchain.com/address/1HQ3Go3ggs8pFnXuHVHRytPCq5fGG8Hbhx
