Holo Beta should launch early 2019. Once sufficient testing has been done, the swap will commence. The details of the swap (step-by-step of how it will be carried out) have not been release. What is certain is that there will be plenty of announcement leading up to the swap and the swap will be open for at least 6 months (potentially longer).
we must be patient to wait for the Holo Beta in 2019, if you want to buy Holo Token buy now, because that is an opportunity to get profit,
because if the Holo beta release, then Holo Token will go up, like most ico when roadmap goes according to plan.
