As for the Lightning network... Did you read
this article saying that there is more Bitcoin on the Ethereum network (WBTC - wrapped BTC) than there is on the Lightning network? I think that Lightning network is far far far from being adopted.
Sure. It doesn't really mean that much though when talking about retail transactions as even the Ethereum blockchain is also susceptible to being congested. Remember the crypto kitties days? Yep. Wrapped BTC are mostly used for staking and such, not really for "coffee transactions" so I don't really think it's right to compare WBTC to Lightning.
