There are also speculations that ETH's value will go down to zero and i considered it as speculations to create FUD among the community thus make the weak hands give up their portfolio that easy. There are altcoins out there that if you wanna do some trading/scalping will give you ample amount of profit in the future but you've got to take the risk by holding them for some time, that is my observation. Just choose the right coins probably those which belong in the top 20 on the market cap.
