Your biggest bitcoin fear
Everything you wrote above is something to be afraid of, the 13 points are all risks and they may or may not happen, but they are all risks in Bitcoin life, we all know that, but whatever happens is the risk we play with internet world.
But before that happens, at least we have done the best for ourselves and also for other people, regarding investment, trading, mining and so on automatically at least and since the creation of Bitcoin until now we have done extraordinary thingsnormal for us and those around us.
Maybe we don't need to think about the 13 risk points that you mentioned above, that we are all aware, nothing in human actions is perfect and eternal in this world, that's the point, do what you have to do as long as Bitcoin is still a digital currency that can be used by everyone, don't think about what hasn't happened yet, remember nothing is eternal.
I choose them all.
