The current list of treasurers can be seen
here. According to the post, the forum currently holds ~1,750
BTC between 4 treasurers.
Paraipans 250BTC are still in there (1PFkqgBBrSKikyyUGDerZMfzvCNPgKrR3o), though they are afaik unreachable.
This is true, as sadly Paraipan
passed away in 2014.
The 500BTC OgN holds as treasurer are also still there (1Eog8UqRFLufC71rBLt2nYgfUDskgxAyVF).
In addition to this, Rassah is holding 750
BTC in this address:
PGP signed and returned to Theymos.
Public holding address: 1HQ8WaKVRYXLBtVdMcYr5SHQ3X9BsLyxa1
The other addresses are either unknown or empty as far as I've checked.
I expect that the majority was used on the new forum software, though I know CIYAM chose to return his holdings to theymos after
an extortion attempt against the forum using them.
If you would like to see what the treasurers list used to look like, there is an archived version from 2014 at
