Quick question on sniping new Binance listing

Been grinding the crypto recreation for a bit now, totally on Binance, and I've nailed some fast flips by leaping on new listings like zero.05 seconds after they drop. Often snag 10-20% good points straightforward, then dump earlier than the hype fades. But recently, I'm seeing whispers about people getting in method earlier like hours before the official Binance spot itemizing, and questioning if that's the ticket to those insane 500% pumps all of us dream about.

Let's use a hypothetical coin referred to as "X" for instance. Say Binance pronounces X is itemizing this afternoon at, like, 2 PM ET. I've heard some individuals are shifting their funds from centralized exchanges over to a Web3 wallet or DEX (assume Uniswap or no matter's scorching on that chain) and scooping up X tokens 1-4 hours early. Apparently, these coins typically trade on DEXes pre-listing if there's early liquidity or airdrops or no matter.

My massive questions:

If I bridge my USDT or ETH over and buy X an hour or 4 before the Binance drop, might I actually see 20% good points and even those wild 500% surges like we've seen with some meme coins? I mean, the liquidity flood from Binance customers might moon it, proper?

Once it's formally listed, ought to I just sell immediately to lock in income, or does low pre-listing liquidity make it a nightmare to exit? Don't wanna get stuck!!

I've caught to post-listing snipes thus far 'cause it's low-risk fuel fees aside however is that this pre-listing play even doable without getting rekt? Feels dangerous AF with potential scams, rug pulls, or simply missing the window. Anyone pulled this off efficiently?
