Recently, everyone has been talking excitedly about sharding and parallel processing. My conclusion is rather cautious: don't get carried away by the narrative; asset security and exit strategies still come first. If it can be done more slowly, then take it slow.

The reason is simple. To put it plainly, with cross-chain transfers and more chains, the most likely points of failure are bridges and liquidity gaps. When I see large transfers on-chain or hot and cold wallets moving on exchanges, people shout "Smart money is coming." I tend to ask first: if they want to withdraw back to the main chain or fiat currency now, which route and step might get stuck? When I test new bridges myself, I start with small transfers back and forth a few times, confirming that issues like unconfirmed transactions, delays, or rollbacks are acceptable before considering increasing the position. Anyway, don’t mistake “being able to transfer” for “being able to transfer safely back.”
