Accumulating address 0x550364CC2e22Da44B5A31e369753552EeB7bc8C5 (if I am not wrong, this is wallet from KUCOIN exchange, assigned to user)
Yes seems like it reading the comments regarding the wallet to which the tokens were being sent to from 0x55064CC... address here: https://etherscan.io/address/0x689c56aef474df92d44a1b70850f808488f9769c#comments .
Also I think the way the tokens are forwarded to Kucoin's main wallet it is very likely that it is one of the Kucoin's wallet.
Regarding the remaining two wallet, I tried to check this one first : 0x5397a8e4efc983627d1e1ba71b0fd92a3b35b3f1 which received 35988.004 OMIX tokens from this bounty: https://docs.google.com/spreadsheets/d/e/2PACX-1vTcCOynndEs4DR7JhDOlbGnTWp4hHkLWzl0JSlmEzy5qIFSIRyhEJGYaAWruqSJO-DTaOeNQ2Sep2hx/pubhtml#. Unfortunately they maintained it with usernames only and there are 25 people in signature campaign who received 35988.004 Tokens. It would be great if you can look into it.
I also tried searching in KWH bounty as well but I need permissionfrom needmoney to access it.
