Well, compare these 2 coins I think is stupid , they are very different of course the advantage will always of course with bitcoin but Ethereum will be the king of ico !
To be sincere ...these are all wonderful projects which has really done great things to mankind ..the impacts are yet to be recover from !!..comparing bitcoin and ethereum; to me is not supposed to be so..since this ledger were created to serve different purposes and use cases!! And again i think Bitcoin is a great store of value and it will continue to lead in the market!
Meanwhile i have them all in my holdings...lol
