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:
I think Ethereum and Doge can still be paired and held in 2023, but AVALACHE and CHAINLINK are not worth it in my opinion. if I may suggest that you join altcoins like Bnb just not to waste your time
BNB is not a very technically advanced coin, it's just so famous because Binance owns it.
Chainlink is very essential in an environment of a large number of Blockchains, which need to be linked. 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.
Avalanche is a very innovative coins, where Cornell University professor Emin Gün Sirer has developed a new consensus mechanism, called Avalanche consensus, making Avalanche very decentralized and scalable.
Avalanche has solved many issues, where Ethereum, Solana or Cardano are still searching s solution.
Of course, Bitcoin is also a valid investment because Bitcoin is an established coin.
