Recently, I've started seeing a bunch of narratives about "parallel" and "sharding," lively like pixel fireworks... In the past, I would see these words and want to rush in, thinking new narratives = new opportunities; now I instead ask myself: what exactly am I buying, can I get out, are my wallet and permissions clean? Especially these days, when everyone compares RWA, US bond yields, and on-chain yield products, honestly, I only believe one thing: no matter how attractive the returns, you must first think clearly about exit strategies and who bears the risks. Anyway, my budget is still written on paper, if I really want to follow the trend, I’ll try a small amount, don’t treat yourself as a hero.
