Do you think Bitcoin will never go up in value?     If Bitcoin value rises even a fraction of what some experts predict then this box could ROI in less than 30 days.    There is always risk with any investment, i happen to believe Bitcoin/Crypto Currency will succeed but i would still never invest more than i am comfortable losing.    If you don't believe it will ever rise in value then you probably shouldn't invest in it, just my thoughts from reading all of these negative posts from several people on this forum.
