It will be very important as usual to make good selections of our coins and while Bitcoin is looking very bullish right now, holding some Altcoins is very important because in a bull run, Altcoins are frequently outperforming Bitcoin because of new technology and innovation.
Here are my selections:

1# AVALACHE

Avalanche had many great news recently as AMAZON selecting Avalanche because of Subnets and Avalanche has seen numberous new applications launching on Avalanche.
In general, Subnets are a huge game changer on Avalanche: https://medium.com/@demirelo/the-era-of-avalanche-subnets-9e94f377cb65

Subnets are a collection of validators participating in Avalanche consensus. A subnet can have costomized Blockchain characteristics but it's based on Avalanche Blockchain. So, a Subnet can be a customized Blochkchain, validated by Avalanche validators who are also required to validate Avalanche's mainnet.
Every Subnet can have different levels of inclusiveness (for example: permissioned, public or private), Such an unique design opens up many possibilities to implement numberous enterprise applications on Avalanche's Blockchain.
AMAZON has detected Avalanche's potential already, when Amazon selected Avalanche: https://medium.com/avalancheavax/ava-labs-and-aws-bring-scalable-blockchain-solutions-to-enterprises-and-governments-295040a34263
In addition, Avalanche is a capped coin, making it scare and people can buy it as a store of value.

Avalanche can really have huge potential and increase in price massively.


2# ETHEREUM
I can see ChainLink here
so mine is:
NEONLINK
Experience a new world of gaming where builders, players and creators share true ownership and limitless possibilities
This is a web3 project to pay your attention to in 2023
Neon Link is a web3 gaming-focused network, dedicated to equipping game developers with the tools and environment they need to create incredible games. Powered by the Neon Link network and NEON coin, our ecosystem provides a seamless platform for the future of gaming

in your style, so it's easier for you to research
let me know what you think

Ethereum has achieved PoS in 2022, making it a top contender against Bitcoin's PoW when combatting climate change. PoS will make Ethereum less wasteful because PoS requires less energy consumption.
In addition, Ethereum is now more scarce as well even if Ethereum's supply has no hard cap but inflation of Ethereum is reduced since PoS.
Ethereum is still strong in DeFi applications, such like Uniswap. More demand of DeFi applications could drive demand for Ethereum.
Only issue is scalability of Ethereum: while Blockchains such as Avalanche have solved scalability, scalability on Ethereum still needs to be coded, which could take lots of time.


3# DOGECOIN

Dogecoin is an original coin and has been around for a very long time. Dogecoin is very famous because of Doge and it will always attract some people to buy it.
Compared to copies, like Shiba Inu or Elon Doge, Dogecoin will always be an original coin, not a cheap copy.
Dogecoin can be promoted easily because it's a timeless coin.


4# CHAINLINK

Chainlink is a relatively new Coin and it gained interest quickly.
Because Chainlink is very essential in an environment of a large number of Blockchains, which need to be linked, we can expect positive investments if we are long on Chainlink. It is likely to increase interoperability as an important factor between Blockchains and Chainlink is well positioned to be a leading Link coin. Chainlink is also supported by Avalanche core developers.
Finally, Chainlink has a massive support among NATO members advertising for it on various soccial media channels.



After all, coins are always speculative but my examples mentioned above are in my opinion a good selection.
We don't know about profits but in a bull market, Avalanche, Ethereum, Dogecoin and Chainlink could perform very well.

What's your Altcoin to look at in 2023?

I’m looking for more too, I’ll be reading this topic, for now I can tell you that NEON NeonLink is planning to grow big as a web3 gaming project
