1. Consensus Mechanism Transition Isn't Instantaneous
The Ethereum Mainnet merge won't immediately complete the PoW→PoS transition. Currently, Ethereum runs dual consensus mechanisms:
- PoW: 90% of network validation
- PoS: 10% of network validation
Key timeline:
- Difficulty bomb delayed to September 12 (source)
- Post-merge, PoW mining difficulty will increase exponentially
- This economic pressure will gradually force PoW miners to exit over ~6 months
- PoW network enters "Ice Age" phase
👉 Understand the ETH Merge timeline in detail
2. Gradual Supply Reduction: Deflation Takes Time
During Ice Age:
- Block time increases → Miner rewards decrease
- Monthly difficulty adjustments compound in severity
Projected supply changes:
- 6 months: ≥50% reward reduction
- 9 months: ≥80% reward reduction
- Current ETH burn rate: ~1300 ETH/day
- True deflation expected by H1 2023
3. Minimal User Experience Disruption
Unlike previous difficulty bomb periods:
- PoS validators will progressively assume validation workload
- Block times primarily follow PoS rhythm (≈12s)
- Maximum 1-2 difficulty adjustments pre-merge
- Worst-case: +2s block time (negligible UX impact)
4. Forked Coin Valuation Depends Exclusively on Exchanges
Historical context:
- 2017 fork craze demonstrated market maturity
- Today's ecosystem overwhelmingly favors mainchain continuity
Key factors:
- Liquidity determines value: Without top-tier exchange support, forks become worthless
- Small exchanges may list for traffic, but...
- Major exchanges likely to protect reputation by avoiding forks
5. Miner Migration: Economic Reality vs. Market Speculation
Economic constraints:
- 80%+ miners use GPU rigs (adaptable to other industries)
Alternative GPU applications:
- Video streaming infrastructure
- 2D/3D rendering
- Cloud servers
Market dynamics:
- Rising mining difficulty → Reduced rewards → Potential operating losses
- ETC lacks ecosystem support for sustained price growth
- Miner migration ≠ organic price appreciation

FAQs
Q: When will ETH become deflationary?
A: Projected by H1 2023 after 6-9 months of gradual supply reduction.
Q: Will ETH forks have value?
A: Only if major exchanges provide liquidity - unlikely given current market sentiment.
Q: How long until PoW is completely phased out?
A: Approximately 6 months post-merge, though mining becomes economically unviable much sooner.
Q: Should users prepare for transaction delays?
A: Minimal impact expected - block time increase capped at ≈2 seconds.
Q: Where will ETH miners go?
A: Most GPU miners will transition to adjacent industries rather than mine less profitable chains.
