Do you see Cardano and Solana eating into the Ethereum ecosytem? I sure don't. Then again, I am all in on Ethereum so I'm biased. I guess we'll find out soon enough. I think ada and Solana are good hedges and will definitely continue to pump in this bull market, but if it can't gain any adoption, then it will dump the hardest.
You can't ignore Defi and even NFT's right now. I wish I had the capital to invest, but buying a condo took all my disposable income.
I'm mainly interested in eventually earning passive income through Defi.
Also, if Bitcoin is able to move past 60k and beyond, then your shitcoins like doge and shibu will also see massive pumps.
