So far no proof of stake coins running with coin-age have been proven vulnerable.
Coins such as ZEIT use PoS version 1 with coin-age.
Proof of Stake Version 1 : Used Coin-Age Proof of Stake Version 2 : Removed Coin-Age and moved to block depth
Proof of Stake Version 3: Used Block Depth and other modifications So far only PoS V3 coins have been shown to be affected.Since Pivx did not actually fix their issue ,
the others using PoS v3 are probably still vulnerable even if they claimed a fix like the pivx team did.
