BTC: You guys in ETH keep boasting about smart contracts all day, but the gas fees are outrageously high, and the network collapses whenever it gets congested. DeFi users are terrified of being exploited!

ETH: At least it's better than your Bitcoin's turtle-speed transactions! The 1.0 system is still using the Stone Age PoW, with a throughput of 7 transactions per second, which doesn't even compare to Visa's spare change.

BTC: At least we're safe and stable, unlike your 2.0 which, after switching to PoS, is becoming more and more centralized, with whale nodes controlling the narrative, and still claiming to be decentralized?

ETH: We can at least support ecological innovation; what can you do besides the gimmick of "digital gold"? The Lightning Network has been pushed for five years and still hasn't been popularized!

BTC: The energy consumed by miners is the price of guarding value; your contract vulnerabilities have been hacked hundreds of times, and the TheDAO incident had to force a hard fork. What about principles?
