What do you say of the new ST20-token based call Polymath? Will it succeed? Will it follow Ether's steps or is it better? State you ideas and make a discussion.
https://www.polymath.network/wizardEven if Polymath manage to offer something more to ICO owners than ETH, it will take more than 1-2 years to move even close to ETH market cap and adoption.
So, no - not in 2018 or 2019.
Pretty much this. If poly takes over eth, it won't be within this year. People seem to forget how long it took ETH to get where it is today. We can't predict the future so we don't know which coin will have as much marketcap but it isn't happening anytime soon and until they've proven their worth.
