[ByronAP]

Please see 9550345879566156771L you can test it with secret "voice fossil rifle lamp enact control way shift april hundred claim tent" the balance shows as 1 and if the transfer fee is 0.1 this account should be able to send 0.9 however you can not as any amount <1 throws "Invalid LSK amount" and if you enter 1 error "Account has no LISK" is thrown.
