These days, there's more talk about parallel processing, sharding, and so on. The faster the chain, the more lively it gets, no doubt, but my first reaction is still: can my money be safely deposited and withdrawn? To put it simply, high APR isn't worth a few points; getting stuck on bridges/contracts or draining liquidity, or having an exit path poorly designed—that's the real trap. The community is still arguing about whether privacy coins and mixing coins are considered "original sins," and as the compliance boundaries tear apart, once assets are tagged by risk control, you can't even withdraw, which is quite realistic. Anyway, I stick to my usual rules: avoid over-leveraging single points of failure, first check permissions and pause switches, reserve mainnet gas, only withdraw when I can, then I dare to enter. Forget it, let's not talk about ideals; first, find the escape hatch.
