this year more than a million people is learning how to use bitcoin testnet and that is good for bitcoin
If you're referring to the "airdrop" spammers, you couldn't be more wrong. That has nothing to do with Bitcoin, and they're not learning how to use Bitcoin. They're learning how to jump through hoops to get made-up BS tokens.
Besides, Bitcoin testnet isn't meant to teach users how to use a Bitcoin wallet, that's pretty much straight forward. It's meant for developers to test the things they're building without putting their real money at risk.
