Well we have a freedom to use bitcoin since it is is still not controlled by government and yeah bitcoin is anonymous but i think we should not abuse the uses of bitcoin because it can affect the image of bitcoin to other good people..
Honestly bitcoin has many good use like the prices buying online is not so difficult and no hassle transfer your bitcoin....
Because of anonymity and no chargeback option they are using bitcoin to scam someone or use it for illegal actvity that can affect the image of bitcoin.
Personally, I am thinking that those characteristics of bitcoin is beneficial to us all, whether you are using it for good or bad, and because of those characteristics, there is no wonder, that even the one with not much knowledge, not interested in bitcoin and don't have a plan to go long term with it users it for their illegal deeds. Think of it, we could buy bitcoin anytime and without asking who we are, So if you want to hide your transactions, you could simply buy the exact amount of bitcoin that you will use and the other side would just convert it to fiat after receiving.
