I found that holding spot positions is difficult, and contracts always get liquidated. To be honest, it's not a technical problem, but rather that the position amplifies emotions. My simple advice: let yourself "still be alive even if you're wrong." For spot trading, break it into smaller parts—don't go all-in when it rises, and don't cut everything at once when it falls; for contracts, it's even simpler—before opening, set a maximum loss, for example, losing no more than 1%–2% of your account on this trade, and close it when reached. Don't try to reason with the market.

Last night, I also casually checked the on-chain routing; 0x routing splits orders into two pools, reducing slippage from 0.8% to 0.3%. But I only placed half a position... because I know that once I get emotional, slippage becomes a "life error."

Additionally, hardware wallets are out of stock, and phishing links are everywhere. At this time, don't take shortcuts by granting unfamiliar permissions. No matter how small the position, it can't withstand a single signature attack. Anyway, I now prefer to earn less rather than wake up in the middle of the night crying.
