While upgrades will resolve these problems, the larger question is how the ecosystem will adjust over time. Will Ethereum be able to preserve its lead, or will newer networks dominate?
Crypto isn't a static industry, if a project isn't able to innovate, it's only a matter of time before it's abandoned by the community. Looking at Ethereum (ETH) as it stands, it's likely to survive & lead for years to come. However, if the stagnation continues, it's possible that Solana (SOL) & BNB (BNB) will emerge as the new leaders.
