Those projects should just choose another network than of choosing BRC20 or ordinals or runes protocol.

They're probably going to succeed but only for a few days or weeks. And don't add anymore to the clogging of Bitcoin's network as they are only causing the fee to go up.

It depends on what you mean by "on Bitcoin"!

Bitcoin protocol and its smart contracts does not have the option to create NFT, DeFi or any other token. So if anybody is claiming they've created a token "on Bitcoin" and are trying to sell it to you, that's a clear case of a scam.
The best example of it is the Ordinals which is the biggest ongoing scam.

However, there are sidechains available that are tied to bitcoin but aren't actually "on Bitcoin" (more like pegged to bitcoin) that have the protocol for more complex smart contracts and allow token creation. They are not scams.
Off the top of my head I can name RootStock (RSK) as an example of such networks.

I don't think so.
Tokens existed for years in this world and they have not had any kind of meaningful success so far. Their only purpose have always been to raise funds, scam people and/or be used for pump and dumps. They have served no other purpose in the real world. So we can't really imagine any success for them in the future either, regardless of where they are built.

I understand your point. It seems there might be some confusion between native Bitcoin capabilities and sidechains like RootStock (RSK), which offer more advanced functionalities without being scams.

They are not layer 2 because they are not bitcoin. Layer 2 means bitcoin that is not on blockchain because it is moved from blockchain to another layer which is called layer 2. Take bitcoin lightning network as an example, you will need to open a channel. If you are using a noncustodial bitcoin lightning wallet, you will need to transfer bitcoin onchain to an address on the wallet just like normal bitcoin wallet, you will pay the onchain transaction fee to open a lightning channel and the remaining BTC that you want to use to open the channel will be on your lightning wallet balance as the coin is transferred from onchain to offchain (layer 2). With layer 2, you are still referring to bitcoin and not any other coins or tokens.

That is true.

Liquid network was created by Blockstream but in a way that federation of parties are involved. It has its own open source blockchain called Elements and it is referred to as side chain. It is called L-BTC which bitcoin developers will argue to be an altcoin. But if it was proposed in BIP and implemented, I think it would have be called layer 2 and be called BTC instead of L-BTC. Another  layer 2 that can be implemented would be the drive/spider chain.

Yes. I read some  of their documentation and got some understanding there. yeah i also think that it is not a pegging if a channel is created. but I have not a  big idea on it. what is your opinion sir??

No, well because I experience playing or doing those what you have mentioned, remember during pandemic in the world DeGi, NFT and gaming in bitcoin and other crypto currency become too popular that many people started soing those things and that's when they discover crypto currency and many people influenced to try digging deeper in crypto currency, I'm also one of the people that become too emersed in DeFi, NFT and crypto currency games, and I'd say I earn a lot from those things its just that I notice that the life span of those things is too short, its because people tend to sell all of their cryptos in the time of ATH and that's why projects like that started to fall apart because people are just selling and not holding simply, they are just farming and selling than people buying crypto currencies, so yeah those what you have mentioned are profitable if you have enter early but the life span of the project is short.

I know one thing that Bitcoin is successful and all these shit happening on the Bitcoin network will be unsuccessful. They are hijacking the Bitcoin network pretending they can compete with other blockchains. Scaling isn't something that can be resolved by saying the word layer 2 it requires a lot of effort to achieve it.

Take an example of Ethereum they came up with a unique idea of creating an ecosystem within the blockchain. They were successful and yet they are congested. Thanks to layer 2 they have achieved a desired results but they had to upgrade their blockchain to satisfy the requirements of layer 2 solution.

Bitcoin network cannot do it without the help from the creator and the core team. As per my knowledge they all never expected things to change so much and that is the reason they planned to stay hidden.

I wouldn't call all of them a scam, sure most of them are because we do not even have to have what it says on the buzzword to be it, like AI coins without AI just the name uses it and project has nothing to do with it, or NFT but just boring copy cat of something else, gaming but there is no game yet etc etc all those examples, those are clean scams.

There are also some that starts honest, but turns into scam over time as well, I guess when people see the money, they assume they will be fine but eventually they just can't hold themselves and end up selling out. There are also some that is not a scam at all, pure honest good intention people but they are just not that good at projects and they fail, not steal anyone's money at all, just straight up fail.
