Ethereum is currently experiencing a weekly low of ~$330. Last week we saw a dip into the ~$280 levels, with a high of $400. It may fall as low as $280, though the longer ETH is out, the more stable it's price will be.
If you have BTC and want to diversify your portfolio, now is your chance to convert BTC to ETH at a low cost. Given that the average price of ETH is around .135 (with a two-day high of .142) you'd most likely be seeing a profit by the days end.
As BTC stabilizes from it's recent surge, and ETH stabilizes from it's decline, the time is ripe to make a quick buck. For those with ETH, don't jump the boat.
As Warren Buffet said (and as many bloggers are sure to remind you):
“[be] Fearful when others are greedy and greedy when others are fearful.”
Good Luck!
