Lately, I keep hearing everyone talk about blockchain builders, bundles, MEV, and so on. Honestly, retail investors don't need to push themselves to become researchers. For someone like me who trades infrequently, knowing that "your transaction may not be confirmed in the order you think" and "a single swap might get front-run, don’t set the slippage too high" and "don’t chase prices on-chain with market orders" is enough. If you really want to do more, there are only two things: use a reliable wallet/router, set gas and slippage conservatively, and don’t treat impulsive trades as guaranteed executions. Recently, funding rates are extreme again, and the group is arguing whether to reverse or keep squeezing the bubble... I’ll just keep track of my accounts, hold back, and wait until the emotions settle.
