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.
Rumours will end up as rumours. And there will be never a coin shich can replace ethereum. It is not just about the technologies behind a project, the reputation is also an important issue. Ethereum is an well-known coins with advanced tech which is enough for the peopld to trust. It has existed roughly 7 years and during that time, many many projects had been planned and finished which made ether more and more famous
So my point is, dont expect any coin to replace ethereum. Just expect it to be itself, express itself and be adopted by other crypto lover. Tezos is an awesome project. I believe it will gain attention from various types of investors
