Let's research both TPS and smart contracts. Smart contract is an old feature, but TPS can be increased. New projects must have something new or faster than others. Only a few years ago, Ethereum could handle the transaction, but now? For some research, every day we are getting new investors and users, where we need more TPS blockchain. Solana TPS over 29k maybe in the future this won't be enough for us. Sometimes we aren't all comfortable in one blockchain even if it's faster and at a low cost.
