Becareful on ponzi and so called investment sites, most time you never get returns as they fail so soon. I guesd trading is advisable if you know the twist and turns. Never been easy!
What can you risk with my U2cloudmining investment system?
All is free now...and people are paid.
if you do not trust you can get your 10000 satoshi in few days.(do not forget to claim the free shares worth 2000 satoshi for free too)
10000 satoshi is not investing, 10000 satoshi is a faucet. A faucet is like a very boring job that does not pay much.
