Tezos is an open source 4th generation decentralized network for assets and applications. It has huge community of Researchers, Developers, Validators and different support groups. It has the largest followers in the crypto space. All of them share the common goal to make it Top 20 crypto currency.
There are rumours in the market that Tezos network will be used for Digital Euro in the years to come. If that happens then its price will sky rocket without any doubt.
Its current price around $2 which is very attractive for investment to yield huge profits in future.
I don't consider Tezos has any comparison with Ethereum. Tezos is now a good coin i know and i use this wallet for holding few XTZ coins. XTZ coins is now cheaper rate and i believe its price will go up as its popularity is increasing but it is not the next Ethereum. Polkadot may compete with Ethereum after the next few years but we can't compare standing at present position. If DOT will take the place of Ethereum in the future, i won't surprise at all.
