Actually financial authorities in various worlds have the same concerns, and they generally refer to it as a high-risk and speculative investment. But they're able to compensate very well so that the case isn't as severe as what happened in India. In my opinion, their minds are very narrow, frozen and selfish, so they cannot take the positive benefits brought by bitcoin. By the way, in previous years the Indian government has tried to do this kind of prohibition, have their efforts been delayed or in vain? Honestly, I don't know the progress of their regulations.
Those officials should first educate themselves what bitcoin, altcoin, cryptocurrency, blockchain are.
If they understand the full nature of bitcoin alone, they won't ban this cryptocurrency.
Many individuals are influenced by the people around them, not knowing the basic technology surrounding it.
If they will truly ban the usage of bitcoin, they will be left behind.
