$WBTC Wrapped Bitcoin (WBTC)
Extra structural risk
Purpose: A token designed to represent Bitcoin on compatible blockchain networks.
Long-term view: Useful for certain decentralized finance applications, but usually unnecessary if your goal is simply to accumulate Bitcoin.
Main risks: Custody, issuer arrangements, redemption, and blockchain-specific risks.
My view: Prefer BTC for straightforward long-term Bitcoin exposure rather than splitting money between BTC and WBTC.
