I would root for Bitcoin, Ethereum, Stellar Lumens, Iris Network, Chainlink, Cosmos, NewsCrypto and other promising coins/tokens with real use cases, utilities and realistic roadmap. As for DeFi tokens, I don't see them grow in the long run. Maybe their demand would die down after a year or two I think because of the hype created by these projects. It's just my opinion only.
This is a huge list and I hope you have adequate knowledge to manage the portfolio but I dont consider Stellar and newscrypto a good asset that worth holding for longterm.
I voted for Bitcoin and next would be Gold, fiat, then Stocks.
Bitcoin for most obvious reasons.
Bitcoin and Gold are the best investment while fiat is a Big No for me. Besides, I can proudly say i don't fiat ever since i join crypto and only change crypto to some fiat i need for some expenses
