Every coin has the same chance to become the " next " Ethereum because Bitcoin too far away. As long they can create higher trust with enough supply and demand, I believe it will become the next Ethereum. Unfortunately, the situation not support your ideas. The market too slow to respond and many people still have trust with Ethereum. Of the record, NEM will become the next Ethereum.
The truth tells it so. That's why every coin to become next ethereum has the chance. So far, I join the satoshi wallet network for testing the rinkeby testnet for totally unanimous transaction and all I could say is that this is really promising and I guess it is not true that it is impossible that transfer of tokens are not unanimously done. Yes you can.
