Can you talk more about the lives Bitcoin has changed? Are you referring to people using it for black market transactions or are you referring to speculators?
Countries where the currency is inflating at enormous rates, countries where the banking system is corrupt/out of date/not functioning, Bitcoin has changed these people's lives. Venezuela would be a good example from this year: https://www.forbes.com/sites/realspin/2017/02/03/why-venezue...
I believe the larger systematic problem with corrupt and non functioning economic instruments is not their corruptability but rather the structures that promote and rely upon on corruption which Bitcoin doesn't appear to resolve.
