Ethereum have smart contracts. And I believe Ethereum have more devs, funds and connections. Of course I want bitcoin to be better but it has to do something and not just linger on being the first decentralized crypto.
Bitcoin dev team are complete assholes who have spent two years making nothing but enemies. On the other hand, Ethereum has a HUGE group of smart guys building scaling solutions, anti energy waste solutions, and real business applications. Further, the community that is deploying on ETH blockchain is huge. What is the language used to program onto the bitcoin blockchain? nothing. What is the language to program into ETH blockchain: Microsofts Solidity (and several other very cool ones). Bitcoin sucks eggs because Blockstream fucked it all up.
