for myself, an acceptable coin in 2018 is ETH. She occupies a leading position on krypto, following bitcoin in many respects. According to forecasts, by the end of 2018 this crypto currency can return the price that was reached at the end of 2017, namely $ 1000 per coin.
Are you sure? I do not see strong reasons to think that this could happen in the medium term, especially taking into account the great competition that ethereum is facing with new cryptos that are offering better features than ethereum, which has motivated many ICOs to be launching their projects through their platforms like EOS.
In addition, the recent fall in the price of ether, as shocking as it is painful, has led many investors to be discouraged by the limited possibility of a rapid recovery in price, which seems to be leading to a lack of credibility in the long-term viability of ethereum.
That is why in my opinon, verything seems to indicate that, on the contrary, ethereum has more risk of being displaced from its current leadership than bitcoin, which seems more resilient in the face of the strong competition that new and more efficent altcoins are presenting.
