Goodness of course there is only one company under one adress?!!
Please post the images of bankera office with working employees. Entrance and inner images. (One of employees must hold a sign "This is bankera office") It will take just 5 minutes to do it using a simple mobile phone. And please answer the other questions mentioned in the post. https://bitcointalk.org/index.php?topic=2091093.msg52086521#msg52086521
Lon Wong, former President of the NEM foundation, was doing Due Diligence at one of Bankera's offices. Is the former president of the NEM foundation credible enough for you? Also Bankera confirmed that they will do interviews with a known YouTuber showing their offices.
