The risk that I can see on holding btc is getting hacked and nothing will be left. There is a possibility that when you are checking or transferring your btc is they have already injected a malicious virus that will take control of everything.
In my opinion, holding the bitcoin is the best thing to do. The only thing which matters the most is your own knowledge. You actually need to be well aware of all the scammers which are sitting around you. Other than this, there is nothing harmful in holding of bitcoins. In fact, holding will help you in making a very good amount of money. You only need to remain calm under any kind of circumstances.
