LOL there's no way that ether will be zeroed in cryptospace since a lot of ICOs last 2 years ago were used etheruem ERC20 and as long as this coin is traded and still on top coins on coinmarketcap there's no way this coin will be zeroed in future
so far eth still provides good use in society, the price may not continue to improve but if the use is still widely used then they will have value, so it is impossible to zero eth prices while many uses still use it. and as long as their use continues, they will continue to live plus more developments are always done regularly
