bitstorm.bizI have found this site from internet..
Is this a safe site to invest my bitcoin?

10-15% is screaming "I will scam you and take your money"
Use your own brain, 10% daily is 3650% yearly. Don't invest in any site that looks to good to be truth, they will take your money and run away with it.
10% daily and doubler is a classic way of hyip. hahaha. i think they must innovate their scheme to a profitable for both investor and them and not being selfish.
Considering the 10% daily and the UNLIMITED payout promise. you need to think many twice if you want to invest in that rate of profit that even bank can never give to you considering
that banks are stable. hahahah
