Recently, narratives like parallel processing and sharding have been hotly discussed again.

It seems everyone is focused on "throughput" and "the next big chain."
I also pay attention, but honestly, what I care more about is where the assets are actually stored and whether they can be withdrawn.
The current testnet incentives and point systems are really good at creating hype; every day in the group, people are guessing whether the mainnet will issue tokens, making it feel like if you don't participate, you'll miss out.
But for me, doing cross-pool arbitrage, what I fear most is that a change in bridge, contract permissions, or upgrade switches can ruin everything—no matter how good the slippage and fee distribution are.
So I usually think through the exit strategy first: if I really want to withdraw, which bridge to use, how much fee to pay, whether I can accept a few minutes of delay, and even whether I can accept losing money and shutting down in the worst case.
That's the plan for now.
