I know that English isn't your first language but can you not read?  It doesn't matter whether they are still at that address or not.  It's the responsibility of the company officers to advise ASIC of any change in the address of their registered office.  Legal notices sent to the address on file are deemed to have been served.  If they don't actually receive the documents because they didn't update their address with ASIC, that's their problem - you win by default because they don't respond.  

There is no way that your lawyers don't know this.  There is also no way that your lawyers cannot locate Ken.  Orange has a population of 40,000 people and he's well known in the town.  What attempts have they made to locate Colin?

Either you're lying or you have totally incompetent lawyers.  If your lawyers thought you could prevail in court they'd have issued a statutory demand months ago.  

BTW, Mr Bitcoin is operated by KenseyCol and they have a different registered address than CryptoXchange.  A lawyer would have found this as their ABN and ACN records are both linked to the KenseyCol record.
