it is all in your head. nobody uses ethereum ever.
the only usage is when people buy it as a token to gamble in ICO and lose most of the times. and since these days ICO is dying ethereum price is also dying with it.
the fall in the price of the virtual currency is not solely the result of government prohibition plans. There is also the saturation factor of conservative investors who are unable to cope with the ups and downs of the Bitcoin price that routinely occurs.
