things to consider

1 - the customer does not want to deal with KYC

2 - they are not requiring that the full amount be from a single seller

3 - they state only large quantities will be considered - what do they consider to be a large quantity?

4 - I still think they mean 100k USD worth of BTC not 100k BTC which is astronomical - who on this planet has the cash to spend close to 1 billion USD on bitcoin. Am not saying there are not people that rich but how many are willing to put nearly 1 billion dollars into bitcoin?
