This is really bad. Whoever has done it, is not a supporter of cryptocurrency to be honest. Because such kind of heinous act actually brings down the reputation of Indian crypto community in front of the government. That shouldn't have happened!
Scammers have no motive except taking money, don't think there is any personal agenda in these.
A scam is a Scam, whoever did this wants the Indian crypto community to suffer. It is a possibility that someone from the Priminister PR team might have done it but, why? As per my understanding, it is also handled by the ruling parties IT cell
Why I do not believe that it is an internal doing is that this is not the first time that hackers were able to gain access to celebrity Twitter handles and this might be another instance.
Whatever happened this incident might hit back the Indian crypto community.
