Based on experience in cryotocurrencies, regarding network security, Bitcoin is still ahead of Ethereum. Likewise in terms of transactions, Bitcoin is much faster in my opinion. The case you make as an example is just a story, but here we want the facts. In my opinion, there is only one complaint about Bitcoin, namely the high price, so collecting it is not an easy thing.
Ethernet chain has been congested in the past year, and gas has increased sharply. Before that, it was a little faster than bitcoin network. There is no doubt that bitcoin has the highest security.
