Effects of BRC 2.0

Now that BRC 2.0 is live on the Bitcoin mainnet, what benefits do other blockchains still have for development and support?

Despite that bitcoin network seeks to employ other newer development like smart contracts interactions, there is still limit the level of smart contracts interaction with the mainnet, this is what makes bitcoin to be much more that just digital Gold into multiple assets layers,  just like we have the layers2 network on other chains, this doesn’t make or take away the presence of other chains.Talking about the advantages, simple it build more liquidity and trust and then scability which have been one of the major concerns of bitcoin network.

Existence of BRC-20 has become pros & cons in the community, not everyone likes this token standard on the Bitcoin (BTC) network. As for the cons, the community doesn't want the blockchain to be burdened with unimportant data that weighs down the network, it will also increase network costs. So, the conclusion that can be drawn is that altcoin blockchain is still something to this day, there are certain advantages to creating a network or using an altcoin network.

There's no advantage for that. What we've seen in the past for its network spam was too expensive transaction fees and very slow in confirmation. So if there will be a 2.0 for it, it will only cause a lot of troubles for most people who usually transacts Bitcoin.

Yup, the spam was bad, if BRC 2.0 gonna do the same thing the fee will increase tremendously. Based on the latest data, most BRC-20 tokens are losing it's worth and turning into dust, goes to show that the data they carry is nothing more than pollution in the network. BRC also carry centralized off-chain indexer risk that goes against the principle of being decentralized. Use bitcoin's sidechain if you want tokens.
