in your opinion which blockchain could beat the Ethereum ... and why
Over the past time, many new blockchains have already tried to present themselves as Ethereum killers. This is the easiest way to attract the attention of investors. But most users have remained adherents of Ethereum due to its high reliability and the work of the team on the further development of the blockchain.
Since the position of ethereum is not as solid as the position that bitcoin has over the market I think that we are going to keep seeing many other coins trying to take away that spot from ethereum, but I do not think any single one of them will be successful, as each year that passes solidifies the position of ethereum in the market and people and the projects running above the ethereum network are going to refuse to abandon it unless the new coin is in fact many times better than ethereum.
