I decided to start my adventure in the world of DEFI with CUB Finance.

I did the same. I wasn't going to bother because I didn't have a Binance account and didn't want to go through all the rigmarole to get one but then, after reading another post I twigged that I could swap half my DEC for the BUSD so that's what I did.

The major risk that characterizes liquidity pools is the Impermanent Loss that occurs when you withdraw tokens from a liquidity pool and their value has changed from the value at the time of deposit.

I still don't really understand this but my DEC was just sitting in my wallet doing nothing so I'm hoping that even if there is a loss I will still come out ahead.
