The changes of ages, the changes of paradigms, have always destroyed the existing order and gave way to the birth of a new one.
It is normal for the power groups that control or have great influence in an established system to try to eliminate everything that threatens their current domain.
It is a reality that can be observed in different historical cases, but it has also been shown that nothing for the advancement of history, so they can delay the inevitable, but all systems fall, all powers are destined to disappear in some future.
For all this it is not surprising that there are groups that from the beginning suspected (very rightly) that blockchain technology and cryptocurrencies would represent a danger to their dominance and the possible start of a new era ... And that is why they will try of destroying that future in which they are not the ones who control power.
