To be honest, as Bitcoin currently stands, the only people who should be suing Bitcoin are those who are willing to take risks and are willing to learn new things. Aside from that, Bitcoin is still relatively young, and as such we likely haven't seen its final iteration. There will always be new technologies or services coming out that will benefit Bitcoin in some way, and thus we have to take some risks to further the project.
Bitcoin is a working progress and everyone who trusts and is willing to invest on it, not just in terms of money for capital for such purposes but also their time and effort will surely benefit from it. Taking risk is always a way of learning things and nowadays that bitcoin is being known to many people it will surely improve and grow and for sure our risks will have fruits in the future.
