Why? How? What's the obvious symptoms of bubble that you're seeing? Or more importantly, why do you think Ethereum isn't worthy of it's current value?
over 40x increase in a handful of months. icos that no one understands selling out in seconds. r/ethtrader filled with thousands of posts a day about buying lambos.
does any of that smell like business as usual?
It smells like it is time to get out and lock the profits. News has it that deposits and withdrawals of some ICO tokens were disabled by the exchanges because Ethereum's backlog is getting too large.
