I'd say it's better to wait till you get a good amount to consolidate. I don't think it's gonna be worth exchanging as it is rn with how small the amount is + the fees coming into play. Also, most exchanges has a minimum trade amount which this may not reach.
Yes, this is the case usually.
However, Binance allows you to trade any amount (i believe that even 1 satoshi) to BNB. Maybe there could be another option like this that I am not aware... XRP usually have very low withdrawal fees as well
