Liquidity pool question for long term holding

Hi guys,

New to crypto/investing and want to ask a query about Binance LPs

So my understanding is that offering a coin to the LP helps with providing liquidity to the coin pair picked, and your reward is a portion of the trading charges that traders in that pair paid.

I’m unsure what impermanent loss and so on means, but I feel it means the brand new worth of the coin had you stored it in your pockets?

If my plan is to carry onto my coins for the long term till some signs of bull market and assuming by then the worth of my cash might be greater than the worth at adding them to the LP, is LP value it for passive revenue?

Real instance: I added 70 THETA tokens to LP, the worth was round $1 per coin then, it showed that I’ll be adding 35 THETA and 35 USDT, a month later, the worth is now 0.75$ per coin, and I earned 70 cents (from trading charges), if I redeem my coins now, will Binance still put 70 THETA in my spot account? I know THETA are cheaper now and I might have technically lost 25% of my THETA portfolio if I stored them in spot, I’m wonderful with that, and was asking whether or not adding my portfolio into LPs if I intend to hold all my coins for a long time and sell when a bull market hits is value it

Or am I lacking another means that I might lose my coins themselves?

Any assistance is appreciated
