Well the two listed servers for the zone in COM do not agree on
which servers are serving BTCGATEWAY.COM and also do not match
those in the COM zone. The additional server for BTCGATEWAY.COM
BTCGW2.BTCGATEWAY.COM is administratively refusing to answer
queries for BTCGATEWAY.COM, i.e. it is returning REFUSED.
All servers for the zone should be answering, listing them in the
NS records is telling the world that they should be asked, also
they and the parent zone should all agree on the NS RRset.
The SOA record for the zone has, at first glance, a bogus email
contact address.
I've CC'd the contacts for the zone this mail.
