“Similarly, Bitcoin, despite having a theoretical limit of 4,000 transactions per second, currently has a hard cap of about 7 transactions per second for small transactions and 3 per second for more complex transactions.”

Really? On what planet? A typical bitcoin transaction is around 225 bytes. There’s one block every 10 minutes (on average).

225 * 4,000 * 600 seconds = 540,000,000 bytes… 540 MB blocks?

What?
