Staking can be pooled just like regular POW mining pools. However unlike POW mining pools you have to give the majority of your funds to a trusted party whereas with POW mining the maximum you can loose is the unpaid balance between payouts which is usually some days worth of mining.
there will be decentralized & trustless staking pools such as RocketPool, where even if a loss of funds occurs the loss is subsidized through the entire protocol.
From what I understand, you risk getting margin called if the value of ethereum drops below the loan amount, so wouldn't you potentially need a large cash pool to offset that risk anyway?
You can stake with Avalanche (AVAX) today for a smaller price which will be decreased in near future. ETH like all other classical nakamoto algorithms have a limit on number of participants in consensus. Avalanche has no such limit on decentralization without sacrificing security or throughput.
Yeah, i'm working on multichain stuff now, and i've pretty much dropped geth/ganache for avalanchego for running simulations… really can't compete with the innovation on the consensus layer… and all the security tradoffs put forth in the eth l2's can be done with coreth for even more "scalability".
With the fracturing taking place now in the eth ecosytem, its only a matter of time avalanche sees more adoption just purely on the technical capability basis.
It's not all about the amount of APY, also which ecosystem you want to belong to and who you trust will improve over time too. Ethereum vs Celsius is a no brainer at the moment.
For me it's more about existing developer activity. In my bubble, 90% of the people are building with/on Ethereum or Polkadot. I usually build things together with others, not by my own, so having a large ecosystem is a requirement and so far, Ethereum is the only community that really fulfills that.
