Yes, buying now the ethereum is still a good thing as a promising coin and let you not be confused by the fact that recently it has fallen very heavily in price because when the market re-emerges the price will again grow.
you cant blame people with their investment since the price is too low again and they are afraid to lose their money they will really investigate for a good investment in the market but since eth is a good coin they can really bought it and hold for a long period of time price will be better soon.
