New ethereum fork named etherinc was introduced as a better ethereum:
reducing block time from 15s to 6s, which improved:
network transaction per second by 2.5x
transaction confirmation speed by 2.5x
miner reward by 2.5x
removing uncle reward
implementing finite supply for mineable coins
Do you think it is better now to invest in ETI than ETH?
There is only one thing what can overbeat Ethereum. Sharding.
If some altcoin could deliver Sharding technology before Ethereum, it would really change the spectacle of altcoins.
