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.
What I believe is that Bitcoin is handy way of trading. Most of the purchasing nowadays is done online. So, for the online purchasers this the easiest and time saving way of shopping, as they dont have to think about exchanging the currency before shopping.
Most of the online sellers accept the Bitcoin, in fact Bitcoin is the most used online currency by the customers and sellers for the trade/purchase. Secondly, Bitcoin has the minimum transaction fee which is good for the user. Thirdly, payment transfers have become undisturbed and fast.
