An interesting bit of 'non-advice', keeping a portfolio simple is a good idea, particularly for early participants. A couple other tokens and platforms worthy of watching are the STX (stacks token), the Hedgehog and Polkadot platforms.

Stacks is a protocol that allows smart contracts on the bitcoin blockchain. This gives BTC even more potential to compete with ETH and similar chains. Hedgehog is another platform that is being established to link all of the accounts/wallets of ones portfolio into a single site for viewing and decision making. And Polkadot is making cross chain linkage a functional reality which greatly improves the potential number of use cases across the metaverse.

As you say, do your own research and build your portfolio to match your interests and needs.
