I think we are at Greed stage, Arrival of CME and CBOE to the scene takes us from 300 billion market cap to the now almost 600 million cap in almost a month! Delusional stage will soon set in, dot com bubble burst at 9.6 trillion. We are now approaching 1 trillion.. Becareful guys. Everyone hope bitcoin will only go higher, but no what goes up must come down. So only invest the money you're willing to lose. Save some money aside to buy when the bubble burst. You might be the crypto Warren Buffet.
