I just want to find a secure and decentralized alternative to bitcoin

Which blockchain could become just as decentralized as Bitcoin?
Where could I store my assets in an emergency if there are no more bitcoins?


Bitcoin:
I don't think we're going to see much bitcoin in the future because big money managers and governments are going to grab bitcoin.
The BRICS currency is coming soon and it will be backed by commodities.
The most valuable commodity that can save the dollar is Bitcoin.
With the Spot ETF, large asset managers such as Blackrock or Fidelity will grab a lot of Bitcoins.

What is left for us then?
Exactly as good as nothing!

Bitcoin is not a currency that we will use for everyday, it is more like gold that will be used to store our wealth.

Ethereum:
Currency will be CBDC or USDC/USDT, as stupid as it sounds, most people let governments guide them and that's why I'm pretty sure most people will use CBDC.
CBDC are created by smart contracts, and there are already some CBDC that will run on Ethereum.

I think Ethereum will dominate the currency industry, the blockchain is in eyes of the government perfectly suited for this.
I also think Ethereum will never bee decentralized as Bitcoin.

Cardano:
They are working on one of the most secure blockchains.
They proceed scientifically before there are changes in the blockchain.
Cardano’s Proof of Stake also works a little differently than Ethereum’s.
They also focus on AI and ML.
They use one of the most difficult and safest programming languages.
There is no foundation that has the power like ethereum.
Hoskinson says Cardano will be 100x more decentralized than Bitcoin.

For these reasons, I strongly believe that Cardano will take over the DApp market instead of Ethereum.

Would Cardano come close to Bitcoin in terms of decentralization? ( by using artificial intelligence and machine learning )
Would they have to switch to Proof of Activity for this?
