I started last October and I invested around $4000. I receive around $30-$40 a day in Bitcoin. Many people complain on these sites which to me seems very bad on their part. It's very legit as of now. Not really any complaints. If people are giving bad reviews then my only advice is... You should know that practically all 'money making' sites on the internet are a 'RISK,' and all good things come to an end.
