The role of Samsung by embedding hardware wallets into their cellphones is indeed quite neat and one step ahead, their aim is nothing but so that their sales can penetrate among cryptocurrency users especially bitcoin, as stated by others. But besides that, there are other benefits that we cannot deny that what Samsung does's really making it easier for cryptocurrency users to secure their funds in the cryptocurrency format far from hacking. In the future, it's likely that other cellphones will follow the steps taken by Samsung, so this will certainly raise a number of questions among smartphone buyers, and when that happens, this's an opportunity for us to answer them while educating them about the world of bitcoin/cryptocurrency (hopefully they are many who are interested), so we can expect the growth of new users in the future.
