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.
Tezos has great potential and quite decent results at this point.
But you can't really say its going to be next Ethereum, because Ethereum is not dead and its developing at the moment.
So in couple years tezos could keep up with current Eth's position, but obviously Ethereum will be far ahead at that point of time.
