We know that ethics and sustainability are in the eye of the beholder. What one person thinks is ethical or sustainable may be different to someone else.Depending on which side of the fence you sit, there is an argument that the anonymity that Bitcoin transactions bring are a benefit to heavily surveillance societies. But at this stage it isnt clear if Bitcoin is just creating a new wealth gap, present across a younger tech-savvy generation.
Tech-savvy generation influences much by what they see in hypermedia. They are not anymore conservatives about what they are looking from it. New generations seem to be unethical because of technology. Addiction and unawareness bring to the evilness of the youth. Technology is not used as a guide to progress, have an ethics and value the cultural identity of generation.
I don't think how bitcoin integrates in ethics since, ethic is more on morality, dignity and reputation of human being. But the way it make sense for me is that, new generation can build up there future by the help of technology specially, the bitcoin.
