Holy smokes. This is getting interesting and inviting. I really want to invest but why am I so afraid. One question. If I do it am I too late to invest?
Not to late, just start small and get to know the sites you invest in.
I saw one thread and op was investing 1 btc each on these top betting casinos betking, safedice, crypto-games, satoshi dice and another popular site I forgot the name. He was posting updates weekly and currently it's on week 7. Safedice, Crypto-Games and Betking are currently at least 15% gains while the other 2 are less or some losses. So maybe you can start with those 3 top investing casino sites.
