ED turns its attention to Bitcoin scam in Nirmal?

What is the status of the investigation into Bitcoin and crypto currency? Nearly 500 people in the district reportedly invested in Bitcoin. Were the actual masterminds behind the scam identified? Are there any details about how many bigwigs are involved?
All the questions cropped up now with the report that the Enforcement Directorate has turned its attention to the scam.
The Enforcement Directorate officials are understood to have made enquiries from local police.
Many government employees and teachers are allegedly involved in this illegal Bitcoin business. There have been reports that some prominent teachers, who have received awards as the best teachers in the State and leaders of teachers’ associations played a key role. There are also allegations that the police failed to investigate the role of a few prominent persons.
The police so far arrested eight people. Have the police uncovered evidence related to bank transactions? The question of why the investigation seems to have come to a standstill.
