Sun Yuchen Cuts 90% of His ETH Position

- He has held BTC as a core position for a year without making any moves, keeping it isolated offline in a cold wallet. He believes the market has yet to price in the risks of quantum computing and AI cracking it.
- He sold 80%–90% of his ETH trading position in the $3,600–$4,000 range, keeping just 20% as a core holding and waiting on the sidelines. He hasn't bought back in so far, and most of the proceeds went into U.S. stocks.

The ETH sell-off in this wave of trading has already played out in the $3,600–$4,000 range. No signs of buying back in have appeared on-chain. A rebound toward the top of that range is likely to meet selling pressure. For ETH to continue serving as a core holding, it remains to be seen whether the founder narrative can absorb the capital flowing out. Those of you still holding, what’s your cost basis, and would you dare to trim if it gets back above $4,000?
