I do agreed on what you said, I saw several times here gave their warning for the newbie that never invest in any cloudmining site but still continue investing into it. It is reall better to invest in trading for us to grow our bitcoin in fastiest way, just be observant to all traders in the different exchange platform. Then you discover the technique in trading.
