Pretty much all alts have risen lately, have a look at coincap.io over several days , you will see literally billions being pumped into alts and bitcoin right now - japan and china, plus media exposure. Or, it's another btc whale pumping another alt for profit? No idea, it defies real logic IMO.
That is, new buyers do not learn the history of the coin they are buying at all? Are they all sheep?
Ever hear of the dotcom bubble? People do irrational things when they think they can get rich quick. People actually believe in day trading assets based solely on drawing lines on charts, and based on no fundamental knowledge of the underlying assets.
