you see what i dont understands whyyyy because if address is invalid the website in this case eobot would not send anywhere? or this gone forever? and i have no chance to get them back
there is no invalid address. there's only registered and non registered keys in bitshares.
same would happen if you make a mistake with a bitcoin transaction, although it's much easier to make a mistake in bitcoin.
bitshares is very easy. user name = address memo = additional message space.
next time send funds to your personal wallet first, and move to an exchange from there. the interface is much better
