once you open a channel always check whats their average fees on amboss
then set the fees high until you see some flow on the channel otherwise you could easily loose a lot of sats! i learnt it the hard way on some exchange channels. they drain your channel imidiately once your fees are too low.
There are many good routing nodes out where which have low in and outbound fees / balanced fees. I heavily suggest open channels to them before open channels to those liquidity sinks like lnbig, deezy and co.
