I just posted about my short term expectation for ethereum price in the coming weeks based on fundamentals.

As to more technical short term trade opportunities, the crypto market is young and naive and I feel it tends overreact particularly on the down side, so 1 strat I use is identify a trend line and buy when it is 20% below that in a big move, and stay buying on the way down, don't get greedy or you can go broke.

In this recent fall I started buying at 165 and continued down to 130, sold on return to trend line at 195. Too early as it turns out but, i am not greedy
