If you really wanna bet on ethereum, consider instead legit projects without ethereum's rubbish, such as ARK (today +10% and set to grow until end of week) or ETC.
ARK i agree is a good project but I suffered major loss on my ETC investments got in at around .0055 btc now the price is almost .001
a lot of eth platform based tokens are good for investing but maybe at this time indeed the price is very difficult to predict because seeing a market that is falling dramatically, I just hope ETH will skyrocket on the market at the beginning of the year because I still keep a little ETH in my wallet
