1/ The ETH/BTC flippening reminds me of the movie Moneyball.
Everybody in baseball "knew" the Moneyball approach would fail.
In reality, the Moneyball approach worked so well that the Red Sox used it two years later to win their first World Series since 1918.
2/ It was a fuzzy belief, not rigorous argument, that drove baseball's common knowledge that the Moneyball approach would fail.
Similarly, flippening deniers have never (that I've seen) rigorously argued as to how bitcoin's proof of work wins vs. ethereum's proof of stake.
3/ Flippening deniers, how does bitcoin's proof of work stay "cheap enough" to keep BTC #1?
The fact is, if both bitcoin and ethereum had a $250b market cap, BTC costs an extra $4b per year just to stay *equal* with ETH.
4/ If bitcoin switches away from proof of work or ethereum's proof of stake fails, then maybe the flippening won't occur.
Yet, bitcoin's cultural identity likely can't be disentangled from proof of work, and the ethereum community has taken the time to get proof of stake right.
5/ I think that BTC and ETH continue to both do well for the next few years.
However, compared to proof of stake, proof of work is too expensive.
That's the main reason why I think the flippening occurs no later than two to three years after ethereum launches proof of stake.

1/ ETH/BTC flippening explained at a mechanical level.
Compared to ethereum's proof of stake, bitcoin's proof of work is too expensive. Here's why.
2/ If we think of ethereum and bitcoin as "corporations", then their "corporate revenue" is equal to transaction fees.
That's the money coming in. Can't pay transaction fees without first owning ETH or BTC.
3/ In PoW, that fee revenue doesn't stay on the "corp balance sheet". 100% of fee revenue, along with 100% of issuance, is paid to miners. Then the miners *necessarily* pay ~100% of their revenue to hardware and electricity suppliers...
1/ imo, the ethereum community has been galvanized and is becoming aligned around the new rollup-centric roadmap recently described by @VitalikButerin.
2/ With the new rollup-centric roadmap, developers can now confidently expect their dapps to scale on ethereum, more or less immediately and into the future.
3/ Before the new rollup-centric roadmap, I think the extended community of ethereum developers felt a general sense of ambiguity around scaling. Should we just wait for sharding? Do we have to wait until sharding? Are people looking seriously at other base layers?
The proliferation of L2s and the success of other L1s won't prevent eth's fee growth, because the L2s use large amounts of gas and/or L1 financial apps will pay huge fees for composability in "city-like DeFi shards", as popularized by @hosseeb.
2/ It may be a common misconception that validator rewards or EIP-1559's fee burn are revenue streams for the broader population of ETH holders. They are not. They may affect the price of ETH indirectly in all sorts of ways, but aren't revenue.
3/ The value of ETH = utility + digital gold + productive asset.
I think that the scope of "productive asset" should be limited to profit that accrues to all ETH holders.
The scope of "utility" should be much broader and includes being a validator.
With the price of ETH surging today, I thought it might be helpful to list the potentially significant risks to Ethereum v1 continuing to run smoothly.
TL;DR DAI above $1 peg for 5 months; bots spamming transactions; Geth (we love Geth ❤️) is 79% of Ethereum nodes
Thread 👇 1/5
1. DAI has been above its $1 peg for 5 months.
Mitigation: ??
You can help: if you deposit ETH into a Maker Vault, borrow DAI, sell that DAI for ETH, and hold the ETH (ie. a leverage long), then you are helping to stabilize the DAI peg. 2/5
2. Bot arbitrage strategies might involve spamming transactions, with an impact on Ethereum's network layer and gas prices. 3/5
I agree with @hosseeb that Eth2 will likely have one or two "city-like" DeFi shards that contain the majority of all base layer liquidity on Ethereum, and have extremely expensive gas prices. 2/8
City-like DeFi shards likely have no direct competitors, including other base layers.
Customers won't want to run serious DeFi on another base layer any more than on a non-city Eth2 shard. 3/8
