Besides Bitcoin, during the past week, we saw Etherum also dip seriously against the dollar, breaking previous supports and moving as low as 530; Is this just Etherum making a correction or should we expect more moves to the downside. HODL or Sell?? 
All falling coin prices include ethereum, it is a common correction due to the nature of the crypto fluctuations. I think the ethereum will be able to get through it well, because ethereum is an altcoin that has the potential and a bright future. A drop in the price of ethereum up to $ 500 is normal. Looking at the history of last year, I believe the ethereum will show a high price this year. So, holding it is a wise choice.
