When I say Bitcoin Classic, I just mean Bitcoin as opposed to the forked versions.
Just say Bitcoin. Bitcoin Classic is part of bitcoin cash. Anyway the LN can do million to billion tps.
For on chain scaling bitcoin, bitcoin can do 39 tps with about less than 3mb blocks. https://steemit.com/bitcoin/@sames/segwit-bech32-batching-others-will-lead-to-bitcoin-reaching-passing-ethereum-on-chain-tps-level
Bitcoin does plan on increasing block size just when segwit has reached its limit.
