I actually heard about this the other day. I think it's a HUUUUUGE step in the right direction. This will help millions of every day users access crypto for all kinds of micro and macro transacting. It will only strengthen the cause it seems. As long as Samsung stays on top of their security!
Nice step, and good marketing for cryptocurrencies, especially for the coins that will be supported by samsung now. I don`t think it will start some big bull run, at least not right away. As I read they plan to have wallet not only for bitcoin, for ethereum too, and maybe some other coin too, we will have to wait and see what will happen. This year is special for huge news like this one is, all we have to do is to wait for realization.
