Auroramine is scam. Because before some days I invest my 0.00115000 btc in the auroramine.and it give 10% of my investment everyday.it's give me  interest for may be 3-4 times.then next day when I try to signed up but the site couldn't respond well.so I try after sometimes but still I couldn't sign in.so I lost my btc.so it is scam.never invest in auroramine.
