No need to worry bro it is a temporary change in cryptocurrency ETH has decent potential and very promising coin in the coin market. It will get back again to its previous rank and hopefully, the market will dramatically change within a few days.
It`s how we need to look at things, in the long run. Fluctuating price means that price goes up and down, who like short term trades can try it, price will moves up and down, in long run I think price of ethereum will grow. Ethereum is still looking for its bottom, I thought it will be at 200 dollars, but it dropped more. Personally I don`t like short term trades with ethereum, it doesn`t have fluctuations I like, but I have couple on a side for future, I think that decent potential you talk about can push price very high one day.
