Looking for advice here.  

Has anybody of you here ever used Legacy Trust in Hong Kong to facilitate large volume Bitcoin OTC trades?

There doesn't seem to be much info about them online. Their website is full of stock images and there is no info about their team members and founders.

I would appreciate it if anybody could shed some light into Legacy Trust in Hong Kong.
Their official company name is "Legacy Trust Company Limited" and their office address is Suite 2303, 23/F, World Wide House, 19 Des Voeux Road, Central, Hong Kong.

A video from their presentation from Consensus 2018, Singapore:
