What kind of future will Matic have with ETH2? Not much need for it after. Matic is good only for short term IMO. For longer term I would go with complete blockchain like Harmony ONE or even Ada.
Im not sure about that. ETH 2.0 will change nothing for those platforms. Matic and ADA will still exist even when ethereum already fully migrated to the POS system.
Even when the tx fees on ethereum got cheaper again and people are still using BSC, ADA, and matic. it's not only about the scalability solution for ethereum will change anything and it's not possible to make it back to the condition before so many people faced a big problem with ethereum tx fees.
But Matic depends tightly on Ethereum it has been built to make Ethereum scalable. Even though they explained in their white paper that they can also scale other blockchains like polkadot or ADA in reality those recent blockchains (polkadot, ADA... ) don't need polygon they are already scalable and interoperable with other blockchains... Polygon is trying to resolve an old Ethereum issue that new blockchain promise to deliver, the only difference is that polygon has already done it and it's used and other are just promising or testing so I think we should follow closely how this will evolve...
