Crypto Currency Trading

Hey so like, I kind of need this explained... I know sites charge fees for buying/selling directly to them. However, what I am confused as sht about is what about when you send cryptos to others. For example, I sell rsgp, was supposed to get $20, but only get $18.43. Like this is really stumping me, because sometimes I receive cryptos, no fee, and sometimes there is a fee. I use coinbase btw

 

coinbase send via email and you avoid fees. Maybe the coin crashed momentarily because it is going mad just now, or they didn't send you enough.

 

Thank you for reply. What if they send with a different wallet? could that affect too?

 

Are you trying to not pay fees? Coinbase is a wallet it’s not meant for trading. There is Coinbase sister site where you can trade without fees but don’t use Coinbase for trading.
