We've had several times over the last 4 months where many people agreed it was the best time to buy alts, but as usually after a little pump they go back to a downtrend.
That is the usual trend. There is nothing new there. For several months already, the rising of altcoins are very short-lived. They do not last for a long time. I hope the old days will take place again when the altcoins' high flying lasts for several days. But I guess, that will happen within the last few weeks of December. Actually, right now we are seeing some greens in the charts for the altcoins. Hoping for a repetition of same bull run for altcoins in early next year.
