Ethereum? no way. ethereum projects that provide the most benefits in many sectors. crypto price movements are reasonable as they are today. maybe for now just about the holder is just considering the actions on the market. But for the long-term prospects I assume ethereum is the best and promising choice.
The best choice depends for what.
However, it certainly is being used for some things right now. For example, some bounty websites are using it to pay bounty hunters instead of with ICO tokens. That certainly makes a difference.
I also don't think that it will disappear anytime soon. Ethereum have a lot of potential and the growth in price per year is being pretty good in fact almost every year. Will it be replaced in the future? Maybe - But not too soon.
