Although this is old news it still makes me sad.
The death is not attributable to Bitcoin, it is attributable to perceived personal failure combined with the perception that suicide is the only way out. I think there is more than one factor that contributed to this perception.
Mental illness/stability issues is a major factor that is being overlooked aswell, we seem to know nothing about her expect she was involved with Bitcoin. Maybe some she loved left her or died, she could have even found out she had a disease or cancer we have no clue. Too many questions to pin it on BTC.
