Plan if there is a government decision against it?
Which government?
Governments above, if Bitcoin transactions regulated.
so far strong evidence they are Canadians.
EDIT: source of the "Chips" may be gambling. in the past of bitcointalk.org some Canadian users operated large Bitcoin gambling sites. guess of the local gambling friendly laws.
EDIT2: at least they are gambling oriented if you look in the FAQ's "Betting". that hardens the evidence of Canadians besides the analysis which I don't want to disclose.
EDIT3: evidence of US citizens is not an option. -->
