Minimum amount to send RVN

Hi, sorry if I'm posting something too obvious ,I've gotten into mining RVN and the crypto world recently.

Thing is, I've 6 RVN in Trust Wallet and want to send them to Binance just to get the feel on how the trading works. But when i try to send them Trust Wallet says 'Network connection lost '. Is it because 6 RVN is too little?

Thanks in advance
