Bitcoin:
Bitcoin is not a currency that we will use for everyday, it is more like gold that will be used to store our wealth.
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.
Cardano:
They are working on one of the most secure blockchains.
Cardano’s Proof of Stake also works a little differently than Ethereum’s.
Hoskinson says Cardano will be 100x more decentralized than Bitcoin.
Did you mean BRICS currency is actually a currency? you've said this currency is backed with commodities, commodities price is unstable, this mean there's a volatility. If the BRICS currency is stable, it's not 100% backed with the real commodities.
If Cardano use proof of stake, it's mean Cardano is less decentralized than Bitcoin. So you're trust in Hoskinson's words? there's no way to verify human words. There's no way to verify Cardano chain is the most secure.
