there are no implications for ethics. because ethics is a behavior related to manners. and bitcoin is a currency as well as real money fiat money so there is no relationship with ethics. ethics are formed not because of bitcoin but people already have their own ethics to treat bitcoin like what.
I Stand to be corrected, is there any special ethics for Bitcoin if I am to answer I may say no because bitcoin is Open to any one who is willing and ready to invest, there is no restrictions to any as long as it's a due process of investment just as others investment like Fiat. I think what is called ethics us generated buy behavior of investor and and speculators, we all know bitcoin is digital currency could that be the ethics?
