Another alt of kakatua aka Alex Jahid is Jahid420- https://bitcointalk.org/index.php?action=profile;u=2755215
I haven’t looked at address connection but his username in bitcointalk and associated telegram account has similarity with Alex Jahid. Jahid is in bitcointalk username and Alex is in the telegram account.
Quoting him, if anyone can find out any address connection. Link to post- https://bitcointalk.org/index.php?topic=5348797.msg57447703#msg57447703
See the telegram user. It's Alex + this year + J from Jahid. Makes enough sense who he is.
