Me thinks they are just looking for unjustifiable reasons to clamp down on crypto. If they say crypto currency is another form of gambling, then stock market is also a form of gambling, because to me, they are similar just that one deals in digital currencies.
I agree, it is one way of devaluing the importance of cryptocurrency. Since these people are frustrated that they can't control cryptocurrency, they are now into spreading misinformation about cryptocurrency and spreading the idea that cryptocurrency investment is akin to crypto gambling. Investment is way different from gambling since investment has several factors to mitigate risk while gambling has none since it is the risk itself.
No matter the amount of misinformation, they can spread their fake news any how they want, but the fact remains that they will still fail at it. How can they say that crypto is a form of gambling? It doesn't even sound sensible.
