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 agree with you a little, but not totally. Because this is not always like launching an altcoin and the chances are 100 percent you will become rich, and if that is true, every single person will start to rush toward this way and start creating their own altcoin and become rich. I know the majority of altcoins in the crypto space are just shit, but considering that creating your own coin will make you rich, this is a wrong statement according to my best knowledge. That is why I believe that you need to research this.
Other than this, what point do you think makes Bitcoin separate from these shit/alt coins of the market? There are many good factors about this, like it has a fixed supply and no more bitcoin can be generated. It is decentralized asast differs it form the traditional financial system, and this is the most liked factor that it communty like the most.
