I see that you are not newbie. So must have some knowledge about bitcoin (who has invented it, how can be sent of received bitcoin, where can be stored and other such things of this level). Now is the time to learn something totally new for most of them like you. Which is much more important than your Black Friday on the story of bitcoin. Its name is halving and mean half of bitcoin in the market in the same time compared with before halving. You must fix well this happening because not Black Friday but every kind of color Friday cannot be able to cause the decrease of its price. Or better. Every kind of color friday cannot stop the increase of its price. Maybe can affect it for a while (being all the colors together) but cannot change never its trend.
