Very simply review of 2017 & what we can look forward to in 2018.
I personally believe BTCUSD is still in a downward trend w/ H&S to be confirmed soon (it's now making lower highs & lower lows). In this context, many coins are going down against USD. With POS coming for ETH, I think it's interesting to look at ETHBTC.
In my previous post wrt ETH, I mentioned the ETH should be more resistant against selling. Against BTC, there's potentially
1. an inverted H&S forming, but volume hasn't been strong enough & the neckline isn't broken.
2. a rising wedge, which may lead to further falls.
In this context, we should use caution. My personal take would be to sit this one out & maybe invest in some cheaper coins with more upside potentials.
