wallet fees and halving

Hello guys, I'm new in the Ravencoin community.

I've been mining another coin (which I won't list 'cause this is RVN sub) and I recently got interested in mining RVN.

I have a few questions regarding this.

Please do not roast me but I'd like to mine RVN and sell to get that other coin I like (RVN more profitable for mining right now). I've read about wallet transfer fees, and the fees getting bigger and bigger as you make more transfers. If I'd mine from let's say herominers, with their minimum payout being 5 RVN, and my card getting roughly 20 RVN/day (according to whattomine), what would be the fee to withdraw the coins once per day considering I already got like 4 deposits that day? or alternatively, if I'd set the payout on herominers to 20RVN in order to do it once per day, would the fee for withdrawal be high?

I always read that mining directly to binance wallet is bad, but if I mean to sell it right away could it be an option?

Also, please pardon my ignorance, I just got to know ravencoin: In your opinion, is it worth to HODL? I've heard about it's first halving coming around, do you have a date/block estimate? If I were to HODL I'd probably cash out on 50% of my RVN every 2 days and hold to the other half, but I'm completely green on RVN fundamentals, I know nothing. Could some RVN enthusiast explain it's uses?

Hope the post was not too long.

Thanks in advance!
