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.
all businesses have risks, like bitcoin. even though we profit from the mistakes of others, this is where our talents are good at reading situations and potential. and I think this is not a fraud, because we have to be good at reading opportunities
indeed all businesses have risks but from the risk that you as a businessman will know your success when doing business, if the business is without risk then there is no challenge at all for you and certainly it will make you bored.
