For me, that's the only real risk. The rest enumerated can be associated with fiat too. So, no biggie. However, Bitcoin is even receiving nice reviews now than it did half a decade or so ago. It's a given that a few years down the line from where we currently are the reviews will be far better than what we have now. The law risk is because a lot of nations haven't seen the need to support Bitcoin through legislative means and certify it a legal tender yet. These nations may not be able to hold this position longer than necessary when they find out they're getting left behind with this paradigm shift if they don't key in. It's just a matter of time, and Bitcoin (by extension cryptocurrencies) will become the ultimate winner.
