Actually there are many ups and downs in the past few days in the byteball bittrex exchange which I don't like much as it makes a foggy situation.
If I hold the byteballs in Bittrex will I receive the (white) byteball airdrop or I should withdraw the byteballs to my desktop byteball wallet in order to receive the byteballs, the white and black byteballs?
Having your coins on any exchange is dangerous. Bittrex will receive the bytes. It's up to them to credit you with the bonus. That said, exchanges do it for free while others charge 5% for the service.
Is 5% worth them doing nothing to receive your money for you?
Also, with them doing it for you, you then don't get any blackbytes.
Less than 9 hours for the airdrop.
