The risk of Policy
The risk of the law
Governments of the world don't like bitcoin at all. Since this is something that is challenging the decade old centralized financial system that is abusing consumers. Risk associated with government policies are valid and have heavy impact on btc price. See China decision about crypto currency and its impact on btc price.
- The risk of Money laundering
I think its quite unfair to associate bad things like money laundering, ransomware etc with Bitcoin. As such things are happening with centralized fiat currencies before bitcoin was introduced. Even today major portion of money laundering goes with Fiat currency.
