Just a few hours ago I had posted that I don't know whether this rally can be sustained or not. The current spike is not accompanied by solid basics. It is solely fueled by rumors. But as of now, it looks like the exchange rates will stabilize at 5K.
I missed my chance when the spike occurred, I thought of taken the profit and re investing, but as I did not know what the cause of the spike could be and since we cant really predict it, I had to leave it believing that whateverpushed the spike in will do it again within the next couple of hours.
But unfortunately, reverse was the case, some smart traders where faster than me and then crashed the price again to what the value was before I experienced the spike, but next time, I will always learnt to put my Technical and fundamental analysis together like you and OP did to arrive at a conclusion, it is not too late though, I am sure another spike will come.
