To me the biggest difference is how bitcoins are created. It takes a great deal of investment in time, effort, money and energy just to mine and produce a single bitcoin.
Unlike altcoins, you can't just print a bitcoin out of thin air whenever you want. Any idiot with a PC can create a new crypto altcoin and print an unlimited or nearly unlimited supply for himself to dump onto the market, whenever he wants. But that's not how bitcoin works.
Imagine having a money printer that prints an unlimited amount of dollars anytime you want. You don't have to do shit to earn it. Just enter the amount you want and press the print button. Voila! You are instantly rich. That's basically how garbage like dogecoin, ethereum, solana, XRP, fartcoin, pepecoin, clowncoin, etc. all work. They are just a digital recreation of the unlimited fiat money system but worse, with no discernible value beyond being a high-tech Ponzi scheme.
What are other differences?

I completely (or at least partially agree), can only add that you can sybil shitcoin networks to get a shitcoin airdrop, and then swap the shitcoin for BTC on a CEX.
