i agree with this and with an update for the price we can make profit and i think trading can be manage from unpredictable job into predictable job because we can have an update so we don't late to know any movements from the market. and yes, we must stay focus with the coins we've selected so we can make the update is work for us and we can know all the happen with the coins.
I don't think that it is acceptable to make trading from unpredictable job to predictable job. Even though anyone can simply predict what will happen for certain charts of alt coins.
Still this is not going be applicable because all predictions are not even reliable because sometimes predictions are failing too.
