whhaaa is this? haha.  

first of all --  they never had 700k users, there's literally not 700k addresses holding BTC in the WORLD right now
http://bitscan.com/bitnews/item/how-many-people-really-own-bitcoins-and-why-does-it-matter
and guaranteed not CLOSE to 100% of people signed up, most saw that even promising 1% a day EVERYDAY for months was an obvious scam.
second of all -- the only thing hyper-inflated whining to your government will do is make them decide to just BAN BTC as it's non-reversible and they can't protect people from getting scammed (your supposed to do that yourself)
don't blame BTC or even Hashocean, blame yourselves for not doing research and blindly throwing money at something you have no proof exists existed
