I cut in half what remaining exposure I had (XBT Provider ETF) at around $35k. As it's been delisted due to UK FCA regs I can't buy back, so I'm closer to all in BSV than ever before

You must be quite the gambler, sgbett.
I would have a difficult time sleeping having any significant value in BSV... anything beyond a few percentages of my total investment portfolio.. not that I even hold any BSV at all, but still I could see how some peeps might want to gamble with a portion of their investments.... but gambling should NOT be comprised of very large proportions, beyond a few percentage points at most.
But you are a BSV HODLer. Your old UTXOs before 2017 can be split, and you can actually “spawn” Bitcoin Cash and from it, and the fork of the fork, Bitcoin Cash SV.
