please lets trace history of fact a bit, Its worth noting that bitcoin was the first to support basic smart contracts in the sense that the network can transfer value from one person to another, but it was limited to currency use case, hence ethereum replaces bitcoins more restrictive language and replaces it with a language that allows developers to write their own programs, meaning that it supports a broader set of computational instructions. now the question is, in respect of the above are the coins you mention of developing their system to better than ETH?
