no. I dont think eth price can go up anymore. even people need eth to join ICO but many ICO had completed will sell their ETH too. price keep freeze. we need a awesome ICO to make people need more ETH
yes it is, but it takes time. it needs big whales or a big investor who will invest eth that will make eth become in demand.
if the rule of demand will apply here, as long as many investors will buy eth the supply will short, and that could be the reason to increase the demand, and it will have a big impact to its price.
