I hesitated for a long time before trying out, but after a few months, I was actually not sure if I was gaining the APR overall because the price of the coins can be very volatile, and my coins holdings also fluctuated accordingly. Decided to withdraw in the end.
I have a rule that I set for myself. I provide only liquidity in pools where I don't mind ending up with one of the tokens or the other. Take a pool like LEN:LENM; both are pretty stable in price and you will get more or less the same ratio over time. If you take another pair where one token is very volatile and tends to lose value, you will end up with much more of this token than of the other.
Yeah I read about that but the prices are sometimes a bit unpredictable. I was pairing another token with SWAP.HIVE and Hive went up quite a bit, and I think that also led to some selling in the other token.
