The article linked from the OP contains this sentence:
Bytecoin is a cryptocurrency which can reliably be used for purchases anywhere and everywhere in the world.
which is somewhat inaccurate. It is true that BCN can bu used in such a way, but I don't see many people are using it for purchases at this time. I would be nice if the adoption was wider, since that would help propel the price toward the predicted optimistic levels. As with the other alts, any optimistic prediction is dependent on the type of market at the end of 2019, which is ultimately dictated by the price of bitcoin.
