Currently the trend is strongly in favor of Ethereum it moved from as little as 0.01 ETHBTC to now 0.1 ETHBTC, which is an increase of price of more then 10 times or 1000%
Best way to trade ETHBTC is holding all your money in Ethereum and whenever you see price drop to a retracement then you buy it, and when price breaks two resistance you sell it.
When you start at 0.1 ETHBTC
Buy at 0.095 ETHBTC and sell at 0.105 ETHBTC
When you start at 0.11 ETHBTC
Buy at 0.105 ETHBTC and sell at 0.115 ETHBTC
Like this you are able to profit from both:
1. LONGTERM TREND of Ethereum
2. Dips from price drops and correction
You get a result that outperforms both underlying markets.
