Just finished mining and now we're talking about sharding and parallelism again, everyone seems very excited. I’d rather keep my fingers on my wallet... While it's lively, the real key is whether you can withdraw when something actually goes wrong. To be honest, before I launch a new chain or a new Layer 2, I check two things: whether there's a "way back" for asset bridges, and whether transaction fees during congestion will trap you at the gate. Recently, someone mentioned increased taxes and tighter or relaxed compliance in certain regions, and with the change in deposit and withdrawal expectations, I can imagine the kind of congestion on the chain where everyone suddenly wants to run. Anyway, I prefer to go slower, using paths that allow for withdrawals, rather than locking myself into a high-concurrency story.
