But it doesn't, nobody has strictly improved on bitcoin (in terms of crypto design) since it was developed. Other cryptos will make claims about their speed or other things compared to bitcoin but never highlight what trade offs they had to make for those
Ethereum is a strict improvement on Bitcoin in nearly every way. Proof of Stake is a much better consensus mechanism all-around. Smart contracts allow for way more use-cases than just money transfer. The account model is much simpler and more intuitive than UTXO. The block time is considerably faster and finality is guaranteed.
It's not a strict improvement though, it's a set of tradeoffs
Wrong. Some other cryptos do highlight their trade-offs. E.g. google "This isn’t to say Grin is better than others, it simply makes different tradeoffs."
Okay, you're right I should have said "most don't" got em
