Just a question,

ive sold first time some heat on heat exchange, on the left corner it shows the right amount of btc on home side nothing.  How its discribed i tried to send the BTC into my btc acc. by following  "choose Asset: BTC (5592059897546023466) Receiver: 9583431768758058558 and Amount: the desired cashout amount"    But when i enter BTC amount it occur "not enough fund"  even if i try to send a much smaller amount including Fees.  So? whats the process?, what did i wrong, how long ive to wait until sending BTC Asset to reciepend adress?  Thanks in advance

EDIT:  Ok, after 10 Minutes it accepted now succesfull, but now ive to wait up to 24hours? until someone manualy send real BTC to my acc?, reminds me of NXT AE with multigateways except its not a full automatic process, controled by heat audits?
