Samsung is a corporate organisation with already workimg systems that have delivered success. Samsung 's acquisition of steemit is just an indicator that our steem is safe., given the value of the organisation.
Many tech companies have invested in other technologies to diversify their source of income. Just like Amazon which started with a core business of conecting sellers of books to buyers. Amazon over the years has successfuly included other products and services such as TV, tablets, games, etc generally most electronics.
The same applies to Samsung which is trying not to over depend on selling mobile phones as a source of income. That is why they are doing research in other areas. As a matter of fact they are already manufacturing cars these are mostly being used in Korea. Samsung is now trying to do reserch and invest in blockchain technology.
