Has anyone tried this form of trading?

Here’s another vid of me doing the same add/remove technique like I showed in my previous post. In this video (sorry about the weird visual bug at the beginning and yes the middle is sped up for convenience), I added liquidity to a coin that graduated on pumpfun to pumpswap and you can see my LP tokens were worth 0.04484 SOL initially and then the coin pumped a bit and when I removed the LP tokens, they were worth 0.04495 SOL. So my LP tokens and my actual tokens I bought to include in the LP both went up in value. Yes I know this is a tiny amount of profit but with larger amounts and on coins that really run up, I wonder if this could be as, if not more, profitable than just normal buying low and selling high because LP providers get a small fee from all transactions of that coin.

Anyone else tried this type of trading?
