2) Ethereum is the best Smart contract creation platform holding major DAPP's in market
For me, so far this is the best use of Ethereum.
That's why Ethereum is still on the highest volume for smart contract cryptocurrency, some other cryptocurrency that has smart contract feature is base on Ethereum or just a copycat, just why I am also a believer of Ethereum.
There is no doubt that there is a chance of ethereum getting a mass adoption too, frankly speaking ethereum works better than bitcoin at this case. And from now I can literally see where the ethereum is heading, I've been seeing a lot of Defi ( Decentralized Finance) though it's not totally decentralized, which is running under ethereum blockchain. Nevertheless, ethereum is designed to do its job on creating dapps, it might be key for a cashless society that we've been wanting for.
Some quality altcoins there also using Ethereum, which Ethereum makes more popular and quality as well. It really built for a smart contract in the first place.
There are many great coins that is running under ethereum network, but I guess people will just look at the ethereum itself since ethereum is the main line.
