Wealthy coming from a fraud couldn't be considered success. A fraud means some people are being abused, used or cheated so others can have their wealthy. But, do you think bitcoin can be considered a fraud?
I don't think so, because all investors have the capacity to understand and learn the basics about this currency before investing. Informations aren't hidden, they are free and public on the internet. When you adopt bitcoin you are aware of all risks. I conclude to become rich by bitcoin can be considered a success.
